Quick explanation:
I'm having an SM420 installed in my stock 3100 to replace the 3-speed column shift, and the rear bearing retainer/bellhousing is too large to connect to my factory torque tube. My question is, were there multiple sizes of bellhousings available? I bought a bellhousing (for torque tube connection) off of ebay and had it installed when I had my SM420 rebuilt by a transmission shop, but now they don't match up with the torque tube.

I am in need of this part for a 1/2 ton if anyone has a lead.

Thanks.
