exactly, if it is an older blazer the body bolts will more then likely break and the metal were is sits will eventually break and push thru the floor. if it is not push button the transfer case shifter has to be extended, along with the auto shifter, and the steering column needs to be extended.
I had a 91’ S-10 with 3" body, t-bar crank and add-a-leaf. The body mounts rusted and broke, and it rode like shit but it was fun.
