This sounds like a repeat of any earlier thread but....I'm rebuilding a '64 FJ40, it has a small block 350 w/ TH350 tranny, what appears to be an Advanced Adapters plate mated to the stock 3 sp. t-case. The t-case sucks! Hard to get into gear, whines, grinds, etc. My question is; What is the best swap for this thing? Did the t-case change at all post '75? Any imput would be appreciated.
