What ford 9" did you use in your model A

Did a search but couldn't find much. When building your Model A what year and model ford did your 9" rear end come from? How was the fit with regards to tire to wheel well.
any pic's?
Thanks

 

Early Bronco 9"s (pre-'78) work well, as they are narrow to be close to the body and have a 5 on 5 1/2 bolt pattern.....

 

i'm planning on using one out of a 1960 f100.

 

Narrowed significantly, I hope...

 

mine came out of a 69 cougar, some mustangs had the 9" but more of the cougars did

 

Defintely early Bronco.

 

I used one from a 57 Ford, fit perfectly. Hard to find now though. Those older F-100 rears are pretty narrow and can be easily redrilled for a smaller pattern. Don't rule out an 8 inch, plenty strong and easier to find.

 

I used a 77 Bronco

 

74 maverick 8 inch

 

57 Ford, it fits with fenders in my coupe. The broncos are a little wider, but not a concern if you are not running fenders.

 

Any of the 55-57 Ranchero's have 56" flange to flange (' rears, as well as tri5 ford sedans I've seen have them..
I have a 9" rear from an early bronco in my Vicki, also 56"...
I seen some 55-up Mercs with the same rear as well..

 

69 Bronco - great size and the 5 on 5-1/2" pattern matched the front '46 hub/brakes wheel pattern on my sedan

 

Early Bronco fits perfect as others have mentioned and axles, brakes, etc are easy and cheap to come by. No custom cutting, etc. Dats what I gots too.

Didn't use a 9 inch in my last build, I took a rear out of a 78-87 G body and used it. Plenty of gear options, and posi units floating around if you wanted one of those. I chunked the factory arms and used tubular ones, with adj. top bars.

 

'68 Bronco - excellent - a little tough to find though.....

 

Used a 9" out of a 77 ford 1/2 ton truck had the big axle bearings and 31 spline axles ,cut it own to 58 inches overall axle to axle and 53 inches housing flange to flange .I also went with strange axles. 16x4 wheels.Hope this helps you out.

 

I bought a 9" Bronco for mine (or so I thought) but it had been narrowed a bit.

They are tough rear ends!

 

57-60 ford f100s are the best cause theyre 9'' rearends, narrow for a model a, and they got a 5on51/2 bolt pattern, thats what im usin on my hot rod

 

If you have a maverick 8" rear. The short axles it has, will work
in a small-bearing 9" housing. These axles are 28 spline and will
work with 9" 28 spline diff's, All you have to do is narrow the
9" housing to the 8" maverick axles. The brakes will also work
with the small bearing 9" housings, "flange is the same".

Just as an alternative, check out the build thread I've got going (listed in my signature) on my AA truck. I'm not sure if the frames are the same width as I haven't compared yet, but I used a 9" out of a early/mid 70's Ford 1/2 ton, complete with spring shackles, frame mounts, and everything. All I had to do in order to make it fit was loosen the U-bolts and pinch the springs in the front about an inch and everything bolted right to the frame.

Of course, I plan to run an old army style duece-and-a-half bed on my AA truck, so fender issues will be non-existent.

 

Mine has a 31 spline 78 bronco full size 4x4 rear end. I took 4 inches from one side, had the axle resplined and everything was great. The 4x4 is offset which makes getting a narrow rearend easy.

 

66-77 broncos had two options. small bearing/28 spline, or large bearing/31 spline. quick way to tell without ripping it apart and counting the splines is to look on the vin tag, usually on the driver door, rear pillar. the "gawr rear" should read 2780 for 28 spline, and 3300 for 31 spline. you can also measure the hole width on the axle flange. 3.375" is small bearing, and 3.50" is large bearing. good hunting.

 

I used a Bronco rear from a 78-81 and it measures 57 inches from backing plate to backing plate, with a 700-16 bias ply tire you can put about 3 fingers between the tire and the body of my two door sedan.

 

Great info guys! I'm on the hunt..Thanks.

 

Another quick way for pre-73 vehicles is to look at the axle end - a big open double-D shape is always a 28-spline axle. A 3-hole horizontal arrangement is almost always a 31-spline axle. In later years, Ford used the 31-spline axle blank & just machined it down for 28-spline applications, so this isn't foolproof for post-73. Pretty much all vehicles with the odd big car 5 on 5" bolt pattern had these axles and any car with rear disk brakes (big Lincolns mostly). But for '60s cars/trucks, it's a pretty reliable method...

 

all good choices , but you do realize that the width of the rear end depends on what size rim and offset and the size of the tire
