Striking Gold at swap meet

I did the same thing at the N. GA Swap Meet at Atlanta Dragway yesterday. I bought an 8 3/4 truck rearend with 3.55 gears for $55....complete drum to drum. The drums are stuck, so I don't know if it's a sure grip or one legger. Don't care! LOL. I will eventually put it under my 88 D100 to replace the 9 1/4 that has Bonneville gears in it.
