    Does anybody know the diameter, length and pitch of the bolts used to hold the half top on a '90 K5. (I would assume they are all the same from 76 - 91.) My truck is at home and I forgot to check before leaving for work this morning. Some reason or another I think they are 5/16's diameter, but was hoping someone knew for sure.

    I know they come with torx head bits originally, but I'd rather just use regular bolts. Fall is in the air and I need to put the top back on the K5.

    Thanks,

    Lance

    5/16" x 18 tpi. The tips are pointy so they self align in the captured square nuts. If you replace with regular bolts I'd make em pointy...

    I've got a set of the factory bolts (with hex heads even!) that I removed from an '88 that I parted out. $10 plus shipping will get you a complete set of nice chrome ones. /forums/images/graemlins/thumb.gif

    Thanks! Got the top back on this morning. Just used stainless 5/16" bolts and lock washers. I just used a screw driver to align things.

    Thanks again,

    Lance
