For 67 I understand the frame mounts are the same for all V8s in a Mustang. The block brackets and insulators are available from aftermarket suppliers. New repops should cost about the same as used originals right now.
I did not know that, I have the frame mounts do you know where I can find the block brackets and insulators? I will start looking harder but I have not seen them except a pair of block brackets on Ebay.
So just to be clear the car was originally a 390 and I am hoping the frame mounts were not changed. So I am looking for the rubber insulator and the engine mount plates. I may have a driver side engine mount plate so if you just have a passenger plate please let me know that too.
