8 3/4" Flange to Flange Width??

[64 SRT8 Dart]

This thought crossed my mind this morning while looking at an A-body 8 3/4 for sale on Craigslist.....

What is the flange to flange width on a 67-76 A body 8 3/4 compared to what would be in a 63-66 A body 8 3/4?

Talking backplate/bearing retainer flange. If anyone knows axle flange to axle flange, that would be nice too.

Figured I'd ask here first, lol.

52 5/8"

Just measured mine 51 7/8'' most call it 52''. this is out of a 70 duster and is now in a 64 Dart

Their the same width

That sounds like a rear that was shortened to use BBP axles and retain the same overall length as a std SBP set up.

52 5/8"

bingo....

This right here is why we need a sticky tech section.

Their the same width

X2...you can go to Bigblkdart and view their tech section on 8 3/4 rear ends diminsions for all[most] cars...but 52 5/8'' is the correct width from factory...

Could be, never know what ya got with used parts.

 

[abodyjoe]

these measurements need to be in a sticky closed thread somewhere around here... the question is always coming up..

thats the chart with the wrong measurements i believe. its saying the abody 8 3/4 is 51.4 flange to flange. no idea where they got that number but its 100% wrong.
