Motor mounts and trans cross member

['65 chevy lover]

I did some searching on the web but, couldn't really find what I was looking for. I have a '65 LWB pickup that currently has a trashed out 283 in it. I have a 383 stroker coming from engine factory and I plan on putting a TH 350 behind it. I know I need to change the trans cross member and would like to replace the engine motor mounts as well. Could someone point me in the right direction to obtain new front motor mounts and a trans cross member! I would really appreciate it.

Thanks!
