Does anyone know what the bolt pattern is on a 66 Plymouth Valiant? Also what other vehicles had wheels that would fit? Thanks
Yeah those wheels were almost as hard to find as the early 60's Buick and Olds compacts (4 on 4 1/2). As hiboy says my 68 Formula S had 14's that were 5 on 4".
think they are offering some of the imitation halibrand big window wheels in a 4" 5 lug pattern , for what its worth...... it would be well worth the money to have the hubs and axles drilled to 4.5 .....easier than a spindle / suspension swap....... brandon
5 lugs on a 4 inch circle. It's nicknamed BVD, as in early (pre '70) Barracuda, Valiant, and Dart. Started with the Valiant and Lancer ('61) and went through at least '72 with drums. Centerline makes some, there are a few of the old slot mags still floating around, the factory Rallyes, Cragar SS, and some custom stuff. Most are 14X6 or smaller. http://mr2.com/TEXT/WheelBoltPatterns.txt
actually up till 72, but same difference. all a-bodys used that pattern till then, 73 came out with discs and a bigger bolt pattern. i have a shed full of damn 4" steel wheels.... ah, rodstracee beat me to it. i dunno where niceville is, but if yer near jax lemme know, you can have some steelies....
I have a set of Rallye wheels with that pattern on my Duster, so I'm guessing they are the ones that are Pre 73. BTW, the lug nuts on the drivers side are reverse thread, too... in case you never had the wheels off. JK
The last year for the 4" bolt pattern was 1972 on the DRUM brake-equipped A-body cars. The '72 DISC brake A-bodies had the 4-1/2" bolt pattern. This same bolt pattern started on the 1960 Valiant and Lancer, and was on all A-body cars through the 1960s through the 1971 model year. ALL 1973 and newer A-bodies have the larger 4-1/2" bolt pattern. I have owned over 40 A-bodies and I worked for Chrysler for some time, so I know this to be a fact. Starting in the 1971 model year, all Mopars were RH thread. Yes, I know, you will probably know of a '71 or '72 that had/has LH/RH, but that is likely from an owner or dealer replacing parts versus a factory deal.
I have seen plenty of dusters and darts with aluminum slots and keystone classics in that bolt pattern. Check out a local mopar club or swap meet.
Best to upgrade to 73+ 81/4 inch rear axle and front spindles/discs. Anything off a 73+ A body will fit. Be sure to use the master cylinder and prop. valve, too. Volare/Aspen rotors and calipers will also work, not sure about spindles, though. While you're at it, V8 torsion bars will help (especially big block, if you can find them.)
I have personally seen a '73 Dart Sport and owned a '73 scamp with the 4" pattern, so the supposed '72 cutoff is not hard and fast, they probably used up some axles and hubs in early 73. It is not as easy as redrilling the axles and hubs to get to 4 1/2" bolt pattern. I redrilled some early a-body axles once, and there ain't much meat out at the edges for that. It worked, but I wouldn't reccomend it. If you have an 8 3/4" rear end, Moser makes axles to convert it, or you can take some b or c body axles and have them shortened and resplined. You can swap in newer disc brakes and 4 1/2 hubs for the front. This article has everything: http://www.moparaction.com/Tech/archive/disc-main.html I have a pair of 8.5" centerline auto drags with a 4" bolt pattern, fairly common on a body drag cars at one time, and have seen aluminum slots, cragars and keystones with 4" as well.
Very hard wheels to find. Mine are 14" of a later model (pre 73 I'm guessing) mopar and are 5 on 4" pattern. I wanted new wheels for mine as well and couldn't really find anything in the time frame I was working with. When all else fails, cap em!
I did the disk brake upgrade on mine from a 73-76 Dart. I still need to convert the rearend to a 4.5". The disk brake upgrade is the only way to go. 9" drums really fade quick. Plus a put the dual MC on too. Single MCs kind of worry me... Plus going from 13" tires to 14" tires is really nice. I think I have a couple steel 14" wheels in the SBP.
You'll see comments elsewhere stating that "100mm is 4", so you can use a metric wheel". Look closely, and you'll notice the speaker is wearing a tin-foil hat. Nothing else fits TIKO, and certainly not 100mm.
Like I said above...The '73 Dodge/Plymouth parts counter book does not show a 4" hub or axle for a '73 A-body. The '72 book does. You might have cars built in or for Canada, too, so that might be where the 4" '73 thing is going. Weird shit happened on Canada cars.
I've seen some people use 'newer' wheels that have the metric spacing which is the 100mm equaling 4" he is referring to. The best thing to do is to convert it to 4.5" and you have a bigger selecton on wheels. Just depends on what you wanna do and how much money you want to spend. Cause when you do the disk brake upgrade...you'll want to rebuild the front end and possibly new brake lines etc...will cost on the cheap at least a 1000.00 and then to convert the rear...you will need to replace the rear end or convert your's over to LBP. Which would require new or redrilled axles and the 10" drum stuff. If you can find an 8 1/4 rearend that would be a good way of going.
The info that Patrick66 put out is generally correct. However, in those days Mopar had a pretty good stockpile of small bolt pattern, 9" drum brakes to use up. There was a good number of '73-'74, 6-banger, drum brake, A-body cars that also had the small bolt pattern until the supply was gone. There was no A-body, 8.75 rears that had the larger pattern, so the rear will have to be redrilled, (I suggest with aftermarket axles), or replaced with a later diff. If you want to stick with the original pattern, more power to you, but an upgrade will really open up wheel choices for you. Roger
A little Mopar trivia, the '68 Hemi Darts and Barracudas that Hurst put together had the larger 5 on 4.5-inch hardware.
I actually found a 7 1/4 rearend out of a 73-74 Dart with big bolt pattern, 10" drums and LBP. That's what I'm going to use for my conversion. It'll be just fine behind the /6. But if you want to put any power to the ground. You'll need an 8 1/4 or 8 3/4. Some Ford rearend will work also.
Well I think the statement should of been 8 3/4 for mid 60s abody cars were 4" bolt pattern. Those are pretty rare. Probably came on the hi-po 273 cars.
73 and up a-bodies either had a 7 1/4 or 8 1/4 rear. 73 disc brake cars had 4.5 bolt 7 1/4's or 8 1/4's and drum brake cars had a 4" 7 1/4 All a-body 8 3/4 rears came from Mopar with a 4" bolt pattern, with the exception of the 68 Hemi Dart and Barracuda Automatics, which I believe used a B-body axle anyway.
What Ajmopar said is true; A-bodied 8-3/4 were 4" bc. Those rears are narrower than all other Mopar 8-3/4s. When I worked at Dodge in 74-75 I know for fact that drum braked A bodies still had 4" bolt circle; I just don't know what year was the last. A good looking steelie is the muscle car dart/cuda deep dish 14x5.5 with 4" bc. They look good with the dog dish caps. Just run the deepdish on the rear and a standard 14 dart/valiant wheels on the front. There are quite a few chrome reverse still out there, but some are too wide for the rear quarter lips on early A bodies. American made a very low production of "T-70" 5 spoke mags that look like a Torque Thrust.
I would think that some of the 73-76 340/360 Sport Darts and Dusters would of came with the 8 3/4 LBP.
