For helping keep this great
old truck web site
on the Internet for over 30 years! and not clogged down with Ads! Again, thanks! | | | | Joined: Jan 2007 Posts: 93 Wrench Fetcher | | Wrench Fetcher Joined: Jan 2007 Posts: 93 | There is a write-up going the other way on this site:
gmcguy.org
The write up is for folks with 3 speeds that want to convert to 4 speeds. I would think the procedure for your conversion would be similar. There are 2 pieces that need to be changed to get to a small hump rather than just one. The section welded at the front of th removable pan is also different.
I hope this is helpful. Regards Steve New Orleans | | |
