The engine compartment is wider beginning in '67, as you know, but I THINK that's pretty much the only difference. You could measure from the block to the inner fender panel to get the difference, if you had accesss to a pre-67 A body. Shouldn't be a problem to find one, or I could measure ours (1964 Valiant.) Let me know if you need me to do that. I'll help however I can; I want to see you get this done (for selfish reasons.)
