    So here is my friend's 1975 K5 that I will be doing the metal work on. He purchased it from Ebay sight unseen in Washington state and had it shipped back to Missouri. He bought this truck shortly after he had gotten into a wreck in his 1987 K5 that he has had since high school. He is keeping the 87 in dry storage until he reaches a point in his life to redo that truck. It will most likely need a front half of a cab grafted in as the accident pushed the firewall back.

    Here is the 87 after the accident.

    At first glance it looks pretty good, but it has quite the amount of ugly. The roll bar is meant for a pickup truck so it sits about an inch higher than the roof line, so you cannot have the top on with the roll bar. The roll bar also has about 12 rolls of electrical tape covering it. It had two different mirrors and tripods on it, the exhaust is two inch off the stock manifolds, into 2.5 inch pipes, generic mufflers (duals), instead of using an adapter, they had filled the gap with weld... Truck was born with a 400, now its a 350, early 70's- divorced choke, thick cast heads.

    The nice is that it had a fairly rare warn winch bumper on it, the dash pad is uncracked, good grille, np203 with a part time kit and warn lockout hubs.

    The worst thing is the body work. Truck was yuba gold with the stainless trim, but was caved and paved and sprayed white. IMG_20190721_202913117.jpg

    They had fiberglassed over the rust in the rockers, the passenger side is much worse than the drivers side.

    Giant ass holes in the doors for speakers, they will be fixed.
    IMG_20190721_221653810.jpg
    Inner rockers and kick panels are gone too, but the rocker boxes and floors are pretty good.
    IMG_20190721_221657012.jpg
    Pulled the fenders and hood off tonight, the drivers fender was an OG fender, but the passenger side was a repop, a bad one too, the top spot welds has completely busted apart.
    The drivers vent bucket is pretty good, but the passenger side has some rust, but the bigger thing is the big ass dent in it. What we are thinking is either someone backed into it with something (hard enough to push the outer fender that far in) or was on a trail and slid and hit a tree. The door is the OG door and has not signs of damage. The truck was owned by a hunting club in WA, so it seems plausible. We will bang it out and get it to where the heater box will seal.

    Wow. That turned out to be one heck of a bondo queen.

    Yeah it is a shame that it was done up that way. A fair amount of bondo was not covering rust or dents, like the drivers door had maybe 3/16 inch of filler in the bottom, but it is straight and not rusted. I guess they couldn't figure out how to adjust the door/fender/hood gaps and used filler instead. They even used a fender shim on the hood hinge... Luckily the stuff like the A-pillars, firewall, floor, rocker boxes, core support and frame are all in really nice shape.

    He paid more than I would have paid (but I am cheap lol), but full removable top blazers in our area are not very common at all. The roll bar looks better in the pictures than it does in real life. The tape is really ugly and they smashed the top of the rear wheel tubs to try to get it to sit low enough to get the topper back on, which it doesn't fit over the bar even with the smashing. He is going to get a real partial cage built for it that will help tie the truck together, cause they are pretty flimsy.

    Lots of parts. Mostly stuff from Tabco, seems to be pretty nice quality panels.
    IMG_20190723_203827112.jpg
    Off topic of squarebodys, but his dads 67 Camaro is pretty bad ass, 509 big block Chevy, 5 speed tremec, fiberglass tilt front, his dad wrecked it in the 70's and finally got it back together a few years ago.
    IMG_20190723_203828887.jpg
    All panels here are from Tabco
    IMG_20190723_203831003.jpg
    Didn't get any pictures, but got the roll bar, inner wheel tubs, dash pad, glove box all taken off. Hopefully tomorrow cutting and welding can begin.

    But the best part is for me the stuff that he doesn't want, like this dashpad, he is going with a custom dash pad so he told me to take this with me. Also brought home the hood hinges and marker lights. I'm not one to argue :)
    IMG_20190724_001707066.jpg
    Only crack is here in the speaker hole, but is way better than what is in my 76 currently, I will spray it to match the saddle interior of my truck.

    Started cutting on stuff today

    Inside is not great, but should be salvageable with a good cleaning, conversion coating, and then some POR15 over it. There is one hole on the mating surface of the inner wheel house, which I addressed with a patch.

    Said patch

    Finished weld, doesn't need to be super pretty since it will be hidden on both sides.

    Got the outer arch tacked in to place, we will get all the new metal in and fit before welding anything solid to allow for any minor adjustments.

    Picked up a 74 GMC donor cab, We will be using the passenger vent bucket from this to replace the smashed one. The rest will be used on my 79 and find new homes with other rusty truck owners.

    Made a door brace using the old panhard bar off his dad's 67 camaro that he had made over 15 years ago, for those who haven't worked with the full top trucks, they are pretty flimsy without a roof.
    IMG_20190805_203359181.jpg
    Cut the rocker open, Lots of rust flakes.
    IMG_20190805_204300941.jpg
    Completely full of shit.

    However the inside of the rocker box is incredibly nice (other than the mouse nests and sand)

    Great progress.
    I will never complain about the metal work I had to do on my k5.
    Mine was due to carpet holding water because of bad window seals.
    No bondo or accident damage.
    Did you or your friend every think this was too far gone?

    Compared to what is around here in Missouri, this is less than normal rust repair. To me almost nothing is too far gone and my friend follows in that idea too. The rust is however in the right places, it's for the most part all stuff available from any re pop panel supplier. The floors, a pillars, firewall, windshieldframe are all in really nice shape. The underside is really clean too.
