    I have just bought a 78 Blazer K10 That has been converted to all-convertible with parts from a 73 I think it was. The conversion looks proffesionally done and all but it also removed a lot(most) of the stiffness in the body.

    Whith the springs mentioned in another post, in a flexed position, I have no way of opening the doors, /forums/images/graemlins/frown.gif and certainly not closing them
    I can actually feel the steering wheel move in relation to the seat.
    How can i simply stiffen up the body?
    How is the original full-convertible hanling flex?

    My '72 was designed as a full convertible and I also cannot open the doors when the suspension is flexing....

    It's normal, but your truck may still be worse.

    A rollcage can help to triangulate and stiffen the body structure to minimize those effects.

    There's only one solution for this....














    ...go doorless. /forums/images/graemlins/grin.gif /forums/images/graemlins/thumb.gif

    But really, check the body mounts to see what kind of condition they are in. Short of replacing those, there's not a whole lot you can do to stiffen things up. Even at that, if you've got a lot of frame flex the body is still going to contort itself. You could add support to keep the frame from flexing so much, but it's not recommended. It's common for it to be hard to open and close the doors while flexing in these trucks (most trucks for that matter).

    Yes I have thought about adding a rollcage but will the body to cage mounts stand the pressure?

    Normal you say?
    Would like a rollcage anyhow.

    Is there any good prize effective complete rollcages or kits to buy?

    your cag shouldn't mount just to your body. Should be some type of mounting setup on the other side to mount to the frame. A cag mounted to the body is as good as the body itself and i know I wouldn't trust my K5 body in a rollover.

    The real converts had extra bracing. On your truck the roof is what kept things lined up. YOU HAVE TOO ADD BRACING when you cut the top on a 76 up. The easiest thing to doo is a full cage tight to the A-piller and tied into the A-piller at the windsheild and the mid piont just below the dash.

    Do a search on "cutting the top", "full convertable" or "going topless". See what you come up with. There are several people who have done this and lots of good posts.

    Ignore Greg in his rust bucket. /forums/images/graemlins/rotfl.gif My 75 with full cage I can still use the doors when fully flexed.

    Uhhhh DAMN! That's pretty cool!
    Is that set up for a Blazer or a truck?How tall is the frame rail efective hight? I like it but I would want to move the body mounts down a little to keep the CG a little lower.

    That is the frame that is under my blazer. Over all the frame raised the blazer up about 7-8 inches. To help with the CG the drivetrain was only raised about 2-3 inches. /forums/images/graemlins/thumb.gif

    Yes and It is a lot stiffer then the factory frame.






    I think it looks cool too. Maybe I should of had it dipped in the Bling Bling juice. /forums/images/graemlins/pimp1.gif /forums/images/graemlins/rotfl.gif /forums/images/graemlins/rotfl.gif /forums/images/graemlins/thumb.gif

    no offense but I hate it. The tube part is pretty cool but then I really look at it and I hate seeing any frame, factory rails or not. If you like it thats all that matters. Just like guys with 12" suspensions, if they like it more power to them.
