1972 Blazer Frame Options

[glenzen]

Hi, I'm new to this forum and happy to be here. A few days ago a buddy got a rusty Connecticut 1972 K5, it has a 307, 4-speed manual and a 4X4. It's pretty rusty to the point it could be either parts or repair and we decided to repair it. I'm gonna attach a video if anyone wants to look at it. Anyways, this is my buddy's dream vehicle and he has been wanting for the past 20+ years and he finally got this K5 basically for free. The frame is rusty to the point on the frame lip we could flex it by hand so, we're gonna need a new frame. Like I said this is a 72 K5, what options do we have as far frame swaps? Is it limited to just 68-72 K5 or do other year/vehicle type frame be of use to us? Or....does anyone have a frame for sale in the Connecticut / surrounding area? Any advice / help will be appreciated.

Thanks,
Gene
