The 8 3/4" rear was also found in V8 "A" bodies prior to '72 as well as larger "B" bodies and most pickups. Check your track width and head to the wrecking yard. Most "A" bodies will have the 7 1/4" rear but the high performance versions will usually have the 8 3/4" version.

Look for:

66-67 Barracuda with 273, 4 bbl carb and 4 speed (probably Formula S)
67 Barracuda with 383
68-69 Barracuda (318 with standard trans)
68-69 Barracuda (340 or 383 standard or auto)
68-72 Dart and Valiant with HP V8
70 Barracuda or Challenger

Good luck.

The 66 was a narrow A-Body or referred to as an "Early A" the rear end width is 2" narrower than 67 and up A bodys.

A 8.25 rear end from any A body will bolt in but wheel offset becomes an issue especially if you use the 4 on 5 bolt pattern. Try and find a 8.25 with 4.5 on 5 pattern, wheels are easier to find.

While you have it out get the relocation kit and move the springs 3" in, this will allow for bigger and more tire/wheel options.
