Re: Newbie questions.
Thats a nice rig. From everything I have seen 67 was the last year for the sm420 so a sm465 should be the tranny it came with from the factory unless something else was ordered or changed. Are you sure it is a C20 it maybe a 30. Check the SPID to help verify. The manual lists a New Process NP435 as an optional close ratio tranny. Is it a leaf spring truck? Is the gray box on the hump the two way radio?
