Weve got a 61 mounted on a 1988 blazer 4x4 frame and it looks like it is a factory setup. we just recently purchased the truck and are getting ready to do a groundup restore. the cab mounts are in line with the blazer frame locations perfect. IM going to replace the front and rear mounts and also both floor pan sections due to the rust. the rest of the trucks sheet metal is like new. I guess the previous owner did not want to tackle it.
