Rear floor replacement
 

Has anyone replaced the rear floor of a blazer here? I mean with anything. Either another one from another blazer, or diamond plate, flat sheet steel or aluminum, anything. I've seen one here done with a truck bed wood kit, but I'm more interested in how it's done for steel.

I know truck short bed sides will work as replacements, but what about the truck bed floor? Can it be tied into the front edge where it drops down? Do the truck bed sills fit under a blazer floor?

I used a donor bed floor out of a lwb truck. The body mount sills have to be changed, or at least the area where body mounts go (like I did).All of the bolt holes match for the wheel house and bed sides with the execption of one near the fuel vent tube. The holes for the body mount bolts are moved over to the valley that is stamped with the half moon area. I was able to use my original piece that folds down behind seats and welded it to the donor floor. Of course the back had to be cut down to the right length and the rear cross sill placed in correct position. My original rear cross sill was trash, so had to use truck sill and fab up correct body mounts, they also will be a different height than truck mount. Everything has worked out quite well, my only problem is I'm not much of a welder and the donor bed could have been better, hope this helps you with a little insight.

I used an 87 pu box. Cut the inner panels out of both the 87 and the 72 blazer. Welded the 87 inners to the 72 outers and bolted it all togeather then welded the front. When I was done you couldnt tell it wasn't stock unless you payed attention to the differences.
