    Hey Guys,

    I am looking at a 73-75 Blazer. I am going to inspect it this weekend to see basically what the truck is worth. I already know about the frame cracking behind the steering gearbox, and some of the rust locations to look for.

    My question is: Is there anything else that these blazers have problems with that i can look at when inspecting it?

    Thanks, SUB602

    Body sag, usually indicated by the doors not shutting smoothly. But that can also just mean the hinges are worn. Nothing too unusual.

    I don't know if this is what you west-coasters run into, but here's what happens in the Rust Belt.

    This is my first Blazer, a '75 K5 I found locally and bought just out of high school. The first picture is just after I bought it. The highlighted section is the part I should have paid more attention to...

    Then I removed the top and it only got worse...

    Until it got to the point where it seriously disrupted my once-decent body lines...

    Make sure you check that area on any Blazer you look at. If the rocker boxes are rotted out (like mine were), the body flexes right there. There's a body mount bushing right there behind where the fender and door meet, make sure you check it and the surrounding metal to make sure it's all there, too.

    Needless to say I had to lift up on the door as I shut it or it wouldn't line up or shut all the way. I eventually just removed the doors and just drove around town doorless for a whole summer. Wish I had some pics of that...

    Sounds like a killer deal, but actually i am doing a partial trade for my 95 Chevy x-tra cab 2wd with airbag suspension. If the deal falls thru and i can sell my truck i will get back with you. Thanks

    You can always post them up on photobucket or cardomain or somelpace too ;).

    My door has a big gap all the way up the door, it doesnt slant in (a little but not really). There isnt much rust on my truck (surpriosing for being 30 yrs old) so I'm not worried about it

    i havent checked on how bad the rusted area is but i figure if its not that bad i can just cut out the cancer and weld in a filler plate. The doors seem to be sagging a bit but with a quick look i think its just the hinges. I plan on taking a real close look at that tomorrow.
