Yeah, I just cut a chunk of a great big log for a support and slid the 420 back just far enough to get the bearing off/on. Of course that was about 35 years ago and I had no idea what model number transmission it was at the time. I just knew it was a big truck transmission.

Oddly enough my little C-10 would have had the SM420 also.

I sure liked those. They always shifted so nice.
