8 3/4 axles 8.75 left and right differences

do you still need the adjuster and lock to bring the axles together with the green bearings?
and the e body rear ends are shoter than b body rear ends and people put them under dusters all the time, and i have some one that is going to move the spring perches in for me.

No. Using the green bearings eliminates the need for the adjuster/lock setup. That's why a lot of guys like green bearings. If you switch to green bearings you also need to remove the thrust pins (clutch type sure grip), or axle spacer (cone type sure grip) from your sure grip unit.

the people i saw using the b body 8 3/4 rear end were using a 71 and it is bigger than the rear end i have and they had pictures of it fitting just fine.

They must have been using wheels with a bunch of offset cause a E-body rear is 5-5/8" wider than an A-body rear. Your E-bod rear is about 4" wider than a stock a-bod rear so it's do-able if you change your wheels and reposition the perches.
