I lucked out and found a junked old chevy pickup with a SM420 in it. Some stupid punks had tried to burn the truck but the fire was isolated to the cab. Not a bad find for an hour and a half crawling around in broken glass.

Any way I have some questions. I was planing to do a jeep T-18 with ford T-18 input shaft swap but have not found hte parts. Now I have free SM420 with that very nice 7 something to 1 first gear. Has anyone here put one of these in there jeep. I see AA makes adaptors but it would be good to hear what is invalved. cost and time wise.

second: I know that It is a SM 420 by the bulge on the pass side. NOw I thought that reverse was down and away by 4th. But in this trany it is down and in by 2nd. Is this normal?

any help would be good. thanks

AA makes an adapter and Novak makes an long as your going to need the adapter run a Dana 300 tcase.

Novak's adapter is much shorter than AA=longer driveshaft, that's the one I have been considering, plus its cheaper:)

Is there anyone here running the Novak SM430 to Dana 300 adapter? DO you like it??
