So here's how I have the mounts. They're from GMCPauls.
Front cab mount:
Rear cab mount:
Front clip mount compared to the originals. This one I'm worried about, I may start a new thread because it really doesn't look close to the original.
Here's a couple threads I found that helped a bit, but not completely as their mounts are not the same in appearance as mine.

Image credits go to him. His front clip mount looks like my new one. Mine also didn't have the 1/8" shims his has.
I have to go back and measure mine now.
