I've been searching all over for a trans mount that has about 1" thickness when compressed/fully tight. Because of some adjustment of engine mounts and a custom trans crossmember, I need to get the tailshaft of a 'glide a bit lower than what normal oem thickness range mounts will allow. I tried the thinner mount used on Muncie manuals, but that one is 1 3/8" thick when tight. I really dont want to run a solid mount. The car does not have a front or mid plate, and it has energy suspension motor mounts. I just wanted to see if anyone had found any alternatives like I described. Thanks!

use the thinner mount with alum spacer to get it where you want it

that way you get it exactly were you want it

You can also fab up something using rubber shock biscuits possibly. I made a mount that way, to support the trans but allow for flex. 25 years, no issues, both mid and front plates.

I already tried the thinner style mount and it wasnt short enough. I think I am going to go with your idea and make one
