A-Body 8-3/4 Narrowed Rearend

Per the above link, the stock drum-to-drum dimension is 57-1/8". I am not sure where this measurement is actually taken from but it is probably similar to my axle flange to flange measurement (except may not account for drum plate thickness) This implies that the housing was narrowed about 1-1/2 inches on each side. My 54 inch measurement was kind of crude, I'll recheck. I am certain that the spring perches were not relocated but I will verify that as well. This was inteneded to be a bolt in affair that would allow the use of 7 or 8in Cragar SBP wheels. I had the wheels as well but they are now sold. Dave
