Rearend and Tranny Numbers

[WILMASBOYL78]

trans numbers on pass side near top of case. there should be a number starting with P.... P=muncie then prod date. The vin stamp will be there also, a little hard to see. Should start 19..... letter code following the 9 is the assembly plant then last 6 of vin. there are also casting part #'s on the diff sections of the actual trans.hope this helps. for photos and more info go to Colvins boo chevy by the numbers.
