Default Re: Small Transmision Hump to Large hump

Thanks Barry. Great photos. I just ran across an article (by Craig Ueltzen, Edited by Jolly) titled "Upgrading a SM-318 3-speed to a SM-420 4-speed" on 6066gmcguy.com. I will let you Know if i have trouble finding a donor firewall section of the large hump.
Thanks. Randy Kaneer
