66 for pickup????????

[vande97]

my buddie has a 66 ford pickup. it has been sitting for about 6 years and it is not in good shape! but we are in the process of gwtting it back together. I am wondering what type of rearend came in this truck? i think it is an 9 inch but i could be wrong!.
Also we finally got the rear drums off after beating them to nothing. I turned one of the axel's and the the other one turned but the pig in the rear did not spin is this right? I have the drive shaft out and i can not turn the pig by hand is this right? what could be the cause for this? also one more question. Where can i find a whole rear end for this truck at a decent price, i want the whole thing to be assembled all the way to the brakes any advice would help alot,

thanks in advance!
