    I have a 73 K5 Blazer and I recently got the OEM rollbar for it. The only problem that I have on instaling it is I am not sure how to bolt it to the floor. I am wondering if I am suppose to tap threads into the floor or if I am suppose to use nuts and bolts. If I am suppose to use nut and bolts I am wondering how I can get to the bolt from the bottom. Anything will help.
    Thanks

    The thing should just bolt down, unless someone has cut and replaced the bed in it. If that is the case I would make a backing plate and put it under each leg of the bar and just bolt it to that. The stock set-up is not a very strong design, so I would suggest you get a rollbar that will bolt down to the frame.

    Leave it like you found it, or better!

    Mm. '73 had no rollbar option; that came in '74, so your truck won't have bolt holes. Not what you wanted to hear, I know.

    Good news is that (presumably) the stock 74-75 rollbar should fit; you'll hafta drill, and IIRC you can weasel down there enough to get some nutzerts or nuts onto the bolts. Might require a 2" diameter arm with four elbows, like working on a Japanese car ;-)

    There should also be tabs that bolt to the door, err, sides, a few inches in from the handles and about the same height. Getting there may be a bitch, cuz I couldn't figure out how to get behind mine.

    HTH ;-(

    B.S. My 73 came from the factory with front and rear rollbars, and the 73 shop manual shows them in graet details.
    LOL

    Okay, so I stand corrected. Geez, lighten up. Somewhere I coulda sworn I had a GM brochure that says "New for '74" and lists the padded rollbar. Also remember I'm talking model years, not calendar years.

    You got RPO codes for both rollbars?
