i have 87 s-10 blazer ,need to know how much of floor to cut out from behind seat to back,i have al ready do the stock floor drop ,looking 4 so pics or info
i just measured 4" back from the seat brackets. on mine the body mounts were in that section of the floor. I cut out the whole back section and replaced it with 14 gauge sheet metal. sorry no pics yet of the floor, but when i get them i'll shoot you one.
if you have already done a stock floor b/d on a 87 blazer,sheetmetal work should be gravy dude.mine is 4.75 traditional b/d and it is cut at the first crossmember behind the seats!
