powerglide mount question

What is everyone running for mounts on a powerglide? I had a urethane mount that felt flimsy when I took it off to switch to a new promod glide. the new glide has a solid mount under it. any recommendations and why?

its in a top sportsman nova 25-2 chassis 2750 lbs 16 inch tire with a 526 cu in BBC. I was running an 8-71 switching to a 14-71 this year.

 

Poly PG Trans mount

We run a standard Polyurethane red powerglide mount under an ATI SG 4 in a ProMod and never have any problems. ATI wanted us to have some flex if the chassis were to flex much and keep anything from stressing the case, and so far has worked good with .96 60's in a heavy car. I had a soldi mount and they talked me out of it and I am sure was a good call-THANKS! Jim from TN

solid motor mounts and solid trans mount will break the case.Dave
