Been lurking a while. Finally posting. Have a new to me project 1952 3600 that was converted a few years ago to an extended cab. Built on a 93 Jimmy 4x4 roller with a vortec 4.3 . Lots of work to be done. The original builder did a good job, then it set out side with no glass for 6 or 7 years, and all the door bottems have rusted out. No pictures to post yet,but hope to soon.
