**Friday update** How do I identify what year my 500ci came out of? I wad told '72 but I need a starter and I need to buy the right one. I have searched and searched. I am hoping a few of you have specific details. Exactly what oil pan do I need (year, make, model), same goes for exhaust manifold. Did you modify your stock transmission cross member? Did you cut your firewall? What radiator and fans did you use? Anyone have engine bay pictures of your conversions? The 500 I have is supposed to be out of a 1972 Cadillac. Any help would be appreciated.
