I searched some posts and I realize that a 80's Blazer body has a different floor than my 74. My 74 is so rusty that it will be cheaper to swap to a rust free body. Anyway, is the floor the same on the 79 with the step down up front by the driver's seat? I think the body bushings may be different but will the back body mounts at least line up? Basically, I am wondering if a 79 Blazer tub will fit on a 74 frame with minor/ major body mount fabbing. I am aware I need to cut the top and reinforce the floor, etc..........etc.... Thanks for any insight on this.
