Ratrodking,
Sorry to have taken so long for photos, been real busy. There are lots of small details that have to addressed in a rear end swap. On my truck, I had to get a conversion u joint because the Camaro rear and the truck had different sizes-not a problem if you go to the right parts store. Be sure and get all the u joint bolts and saddles from the junk yard. Also the camaro rear is "shorter" than the 55-your driveshaft will be about 1 inch too short. Here is a photo of the u joint.

Get the lug bolts too. I was going to get a rebuild kit for the wheel cylinders. The parts guy said he could sell me new cylinders almost as cheap as the kit. Then he asks if I want metric or standard. I took the standard. Then you can use all the brake lines off your original rear ends and not have to replumb everything.
Just a few thoughts to help you along, good luck.
