Gen IV 5.3 Vortec in 1997 Tahoe motor mount questions

I think it will work that way for you. If those are S&P plates they are pretty thick.

here is another pic, with a `07 motor mount on a '07 Suburban. I still see a way to use the AFM mounts when the '97 frame mounting area is converted...

just in case I have to step back, has anybody a drawing of the adaptor plates to do it the Gen III way

Here ya go, you can shift the bolts if you want to offset the motor. This is what I used to build my plates out of stainless.
