Removed the hitch, fuel tank skid plate, fuel tank, fuel lines, body mounts and cut out all of the rot

EFI fuel tank, took a pic of the baffle inside since a lot of people want to see what's different about them. In tank pump, all new nickel copper lines and added a vapor canister. New body mounts, squaring everything up before welding.

I saved as much of the original hardware and steel as possible. Rewelded in the anchor nuts for the mounts. Added a trap door for the fuel pump which will come in handy I'm sure. The ribs on the replacement panels never line up perfectly but it will be carpeted again anyway. After I finished all of the structural repairs, I did a spray on bed liner followed by sound deadener.

I cut out all of the rot in the front floors, welded in new floors and put this Kilmat down over everything. Sorry to all of the Matt's out there  ;D I took a video of the sound difference with and without. Major difference!

Onto the firewall, heater box and Evaporator. The firewall rot is a result of the cowl seam sealer letting water in, which I also repaired. The cowl used one full tube of seam sealer, plus you lose some with the hose attachment. New heater core, firewall is solid again but I have to make the center section pretty after I pull the engine. The hard part is done. I layered the firewall with the Kilmat and then a new insulation pad.

The mufflers and exhaust on this thing were like 1.5" pipe for some reason and they were filled with dead mouse so I lopped them off. Using some 3" aluminized pipe I had in stock, I made muffler back exhaust. I'm not going to bother with the front section until I'm ready to drop in the new powerplant. I still have a lot of work to do and didn't post pics of a ton of other work I did, but I'll get to more pix later. Last night I took it for a burn up the street and the u-joint straps snapped sending the driveshaft  into orbit. I got it back home and am waiting for Napa to bring me new straps and u-joints  8)

Cant wait to see that thing finished. Those floors are almost as bad as my Blazer. I hope you remember to put all that insulation back in the AC box so it functions properly.

Did you get floor pan patches or find a donor truck bed?

Pull insulation back? No insulation was left after I stripped it. Sounds like you guys can't see the pix? Let me know if you can't. Everything was stripped to bare metal and either patched with new panels or I fabbed new pieces. The firewall was stripped, repaired and new insulation along with rebuilding the Heater/AC box was rebuilt. Just got back from Cape Cod and we're supposed to get slapped with a hurricane. Let's see what happens next!

Great progress! I assume you put kilmat on the cab roof also? Then you glue the head liner and insulation on it?

There is no cab roof or headliner on 73-75 Blazers and Jimmy's. I wouldn't put it on the roof if it had one though. I took a video of with and without the sound deadener and it makes a big difference.

frotosride, I misread what you wrote, now I get it  ;D

Got it, I see it on the picture now too. Saw an '88 Blazer at a car show today. It's top starts after the front seats.
