1972 blazer help

[briank]

Hello, I'll start off by saying I'm a suburban guy but have always liked the Blazers and Jimmys. That being said, there is a guy in town that has a 72 Blazer 4wd w/a running 350 (4spd) for sale and was wondering about some of the parts availability for it. It has typical rust (came from Utah previously so it must have been in the midwest for awhile!) The rear double wall top hatch is missing the latch and handle, is that available? Doors are toast and I'm told p/u doors will work if you cut them around the window channel. Thanks for any help!!
