Does anybody know the correct part or parts numbers for 1970-74 Camaro SS 396 or Z-28 trans mount for TH 400 trans. I do not want to buy reproduction because they seem to be universal mounts for several applications (TH400, TH350, & Manual trans,). The lower wider holes are oblong, not round. So far I have 2 part numbers for TH400 trans, #334529 and #3913498. One guy said his book said #334529 is for 1967-69 camaro, but does not mention 1970 camaro. The #3913498 seems correct, but are their superceded part numbers. Thanks John Gialanella.
