Motor Mount Help

I have done this a couple of times now. Last one was an 89 Dippy 318 that I put into a 63 Valiant. I used the 65 Barracuda 273 mounts, but had to weld on a triangular piece to the pass side mount and drill out the hold for the bolt to go thru. I also had to modify the firewall around the heater fan on the 63, but you don't need to worry about that on the 64 and up cars. Us the 273 mounts if you have them and get the one modified. No biggie.
