Most T-Bucket owners want/or have a 9 inch Ford rear end.
The 57 Ford is the most desired one. It is narrow, has a drain plug in the bootom and looks the best

rears

i'd also be looking at the ford 8".. mustang, falcon, maveric.. they are in the 55" range. thats the inside of backing plate. i honestly feel u'd be hard pressed to break an 8".. a friend had a blown 750hp on a bucket with an 8" posi... i like the '67 & '68 mustang for the axle tubes are the same OD the full length, were as the '65 & 66 are a step down... plus u don't need to cut those rears.. great size...

The main thing to look for is a flange to flange measurement of 54 to 56 inches. I've seen both 8 and 9 inch fords, S10 rears, 8.8 fords, and 8 3/4 Mopar rearends used.

Ford Explorer rear ends are about the right width, cheap and generally tougher than the S10 rears. It is pretty easy to find them in limited slip and the gearing options are good too.

A Ford 9" is overkill for most 2000 pound 'buckets and why Total Performance used the 8" out of a Maverick/Comet/Mustang for their entire run according to the former owner. Easy to work on, fair number of gear ratios to choose from, OEM and new and parts are relatively easily available. Unfortunately, these were not made after about 1980 and the entire rear end is getting hard to find as salvage yards clear out old stock. The later Mustang/Exploder rear, while it fits nicely, doesn't look 'pretty' with the 'tin' back covers and exposed bolts and neither do the 10-12 bolt GM - you do see the entire rear, wheel to wheel under there - but many do have an integral e-brake as well as discs. Toss up!!

It's uncommon but I have started to see Toyota axles being used. There right in that 56-59", and have a drop out center section. 2wd shares the 5x4.5" bolt pattern with Ford and Mopar. has a couple odd gear ratios available like 4.30 and 3.58, but 3.42 and 3.73 are also available. They made 7.5 and 8" rears, and altho most 2wd's got 7.5", they could also get 8".. bit diffacult to decode, but there plentiful and would look right...

Expo 8.8 wouldn't look too bad with a finned aluminum cover.

I'd use an 8.8 out of an explorer. You can even find them in most ratios without having to change them. 355 up to 410 are really common.

I put a GM 10-bolt out of a S10 in mine. I later put in a Eaton Detroit Truetrack in this unit. My T-Bucket weighs 2040 pounds with me in it. Before I put the Truetrack in it, you could spin one rear tire without thinking about it - no weight on the rear end in these things. They leave a very light (but long) patch of rubber unless you're holding them in place for a burnout. The Truetrack helped with the hookup and I don't have to worry about the clutches in a conventional posi setup.

I tried to keep the weight on the two axles equal when I built it. Using a larger (heavier) axle made that difficult. If you're worried about breaking your axle, you can also beef it up with a differential girdle.

Bottom line, these cars are light and therefore don't see the driveline stress that much heavier cars put on their drivelines.

I have heard about using the Explorer 8.8 rear end. What year(s) are we looking for? I have found that most hot rod applications are based on older parts which were readily available back in the day. If I have to go out and try to find a rearend out of a 57 Ford, it's going to be a long time building this baby !
