updating the motor and trans in my 47 chevy coupe. 261 and a 5 speed out of said s10 and the rear end. i want to run stock 16 inch wheels because of the accessory caps that i have for them. how can i fix this dilema?!?! custom made wheels? some sort of adaptor? overlooking the obvious? and since ya love pics on here so much.pic of said car and caps.
You could maybe have the axles redrilled for a 6 lug bolt pattern...maybe. I think the easiest solution would just be to get some 16" wheels.
you could try re-drilling the bolt pattern in the S-10 axle flange IF there is enough room to do it. how wide is the S-10 compared to the stock rear? you may be able to use a quality wheel adapter
You might be able to switch out the axles.But not to sure with wich ones.Or try calling trans dapt for the adapters.Not sure if there is a 5 to 6 lug out there.
Isn't a 4wd s10 rear six bolt? I think it is different from a 2wd version. The 4wd is also a little wider.
Nearly all S-10s used the wimpy 7.5" axle. Do you REALLY want to put this under your car? In any case, you need to redrill the axles AND the drums, or get new axles from a company like Moser.
I doubt a street driven stovebolt 6 will break it, when a 200 hp 4.3 doesn't. What I would do, is get a 6 lug Isuzu Nissan or Yota rearend and weld new perches. Plenty strong, common, and way cheaper than custom axles .
Not true. The 4.3 v6 models had a much stronger rearend. The early 7.5, or whatever they called it, WAS garbage though! I think Pasadenahotrod has given you some good info to follow up on. Remember that, in Toyota's case at least, there are several width rearends depending on truck model and year. Don't write off the potential use just because you first find one a bit too wide or narrow. Hopefully there will be one in your size! An Internet search should get you the info on the different versions and cut down on the junkyard crawling. Cool car!!!!
I Not true, I believe 4.3's also used versions of the 7-1/2 or 7-5/8 except for some of the limited edition ZR 4 wheel drive trucks that had a 8.5 10 bolt rear.I have personally seen the 7.5 in 2 and 4 wheel drive S10's and Blazers The small axle isn't the strongest but one set up properly will handle 250 plus hp on the street.
What he said. Add Mazda B2000 and B2200 pickups as well. Wrecking yards are full of em, and they're bullet proof. Brian
Are these 6 lug Isuzu, Nissan, and yota, bolt patterns the same as the old chevys rims? I know the cadillac escalade wheels fit the old nissan trucks....dont know how that helps but you never know.
Not true...because "you believe"? Thats an interesting amount of self confidence! LoL The later, larger rearend might be the 7 5/8 you mention. I've never seen a small rearend (7 1/2?) behind a 4x4 4.3. Never did work on any 2x4 pickups though. Maybe the 2wd Std cab, short box 4.3 pickup uses a small rearend??? I dunno...but I doubt it. Regardless...IF I needed one, I would simply look at all the common S10 rearends available in the width I needed and take the larger one, from the newest, largest engined, fuel injected vehicle available. I don't know what GM calls them, but if thats the 7 5/8...so be it. The larger rearend IS a stronger setup than the small one...and I say that from personal experience. (not to mention common sense! ) Besides, as far as this thread goes, its ALL a non issue anyway and we're just discussing hogwash. The man HAS his S10 rearend and it matches his engine...but he needs to have something to hold a 6 lug wheel. NO S10 has that unfortunately... I missed "53 sled" saying the Toy axles etc could work even before "Pasadenahotrod"! Sorry...
I put a 12 bolt under my 53 chevy PU from a 65 chevy half ton. I think it was the last year for a 6 bolt half ton from GM It's a 3.53 to 1, I believe. $100. Weld on perches and it was ready to go.
The 7 1/2 and 7 5/8 axles use the same differential and bearings. The only difference is the O.D. of the ring gear.
I did the same thing under my '41, but i think my 12 bolt is slightly older than '65. Cost me £200 and found it pretty easy - there must be loads of them for little money over there.
isuzu trooper should be about the right width and disc brakes too. watch gear ratios mine has 4.55. maybe one from an automatic?
In searching for why I'm confused over this, I found that your absolutely right in what your saying! Your also right in saying that many 4.3's used the 7 1/2 or 7 5/8 rear axle. I really though that the 4.3 used a larger assembly exclusively. Never too old to learn! LOL MY confusion came from the fact that many S10 4x4 4.3 Blazers (but apparently not all) used the larger 8.5 axle assembly. It wasn't just the ZR4 version. (I think they might have been wider? The ZR4 is the one with the flares, correct?) Apparently the 4 door Blazers I've worked on over the years, inc engine swaps, were using the large axle assembly! I've seen the 7 1/2 assemblies grenade...but the 8.5 seems to be rock solid, as you'd expect. Bottom line...I still stand fully behind this statement: "Regardless...IF I needed one, I would simply look at all the common S10 rearends available in the width I needed and take the larger one, from the newest, largest engined, fuel injected vehicle available." Thing is...the "looking" will be a bit harder due to the increased variety. It's NOT as simple as just looking under the hood! All the best!
I've done this but I had to purchase some 1/4" spacers intended for a 4x4 as the Chevy wheel centre hole is smaller than the axle centre.
Thanks for the argument guys haha! im gonna have to look into the 65 chevy rear end and being from a truck i wonder if its gonna be super wide for the 47 coupe. 49-54 wheels went to 15 inch enjenjo. thanks sawzall. have the motor and trans still need a rear but nothing is set in stone as you can tell. i was throwing some ideas around and i appreciate your guys time and ideas i will let you know how this pans out
Place is too damn quiet anyway...LoL For sure let us know what you use and how it works! Someone else WILL need the info eventually...
