205 rear support???? HELP

[80chevy_shortman]

ok iv seen horror stories on 205's cracking the adaptors and etc because of the weight., id like to go ahead and support it and prevent a problem. iv seen diy4x and off road design sell mounting kits for rear bearing cover, however iv read that these mounts are a bad idea because the case is basically mounted to where there is no flex from tcase and as the trans an engine torque flex, it causes in my case for my th350 to crack bellhousings because its the weakest point,........................???? question is can I get ideas on how to support rear of 205 and still allow flex and any ideas on some custom cross member to mount the support

Behemoth drivetrain--a vendor here, makes a rear support that replaces the rear bearing retainer housing. This in my opinion is the best bet, mount the bottom of the trans with a poly bushing on a solid crossmember then mount the rear output on a poly bushing on a solid (attached solidly to the frame) crossmember. This keeps the twisting down the centerline of the drivetrain and keeps it all equal. Where people screw up is A, not supporting the heavy as shit 205 at all, B, running solid or stiff poly motor mounts and rubber mount the trans and tcase, or C, mounting the trans/tcase solid to the xmember and putting bushings at the frame ends of the xmembers.

I would have to agree.
Its also the only mount that will let you adjust your clocking without reworking your mount. If you get a lift later on and you want to clock the front DS down you would just loosen the clamp and retighten when done. I've heard of some people running a crossmember above the 205 and using our mount to "hang" it.
You can rotate the mount to put the tab where you need it, trim it to the right length and weld the tube on.
