transmission mounts

I have 68c-10 with a Muncie m-21 swap. I'm needing mounts that attach to bell housing to cross member can't seem to find any. Help would be appreciated thanks

Re: transmission mounts

I believe LMC has them. Pretty sure you don't want to go that route with a M21. You should get a auto x-member and mount on the tailshaft. If your bellhousing is for the 4-speed truck trans. SM465 the bearing retainer (big hole) is 5 1/8", while the bearing retainer on your M21 4 11/16". I believe the SM420 bell is 4 11/16". Or a car bell. Or aftermarket. Not sure how the 3-speed saginaws are mounted. I always assumed on the tail. But I might have read not. Anyway the bolt pattern for trans. is different between M21 SM465. If the Saginaws indeed do mount at bell to x-member. I wouldn't leave an aluminum case M21 hanging by the ears.
