    Ok, I just got the body mount kit from Classic Buicks, but there are no bolts.
    Does anybody know the correct size bolts needed for a 1966 Buick Wildcat convertible? Most of mine were pretty poor, and all 4 at the rear of the car broke. I thought the kit came with the bolts. I should read the description closer the next time! (My bad!) I am going to the garage shortly to see if I saved any, but I'm almost positive I chucked them :rant: . I know, save everything, bag and label, yada yada yada....... It figures, the one things that I "think" I didn't save....... If I find one of the measurable ones, I'll post back, so somebody doesn't go out of their way to look this up or measure something for my stupid mistake.
    Any help is apprciated.
    Thanks,

    Should be 3/8-16 or 7/16-14 bolts. I believe the length should be the same as the Skylark versions which are about 3.5-4"

    Thanks, George!

    Thanks for the information. I'll take it, along with the one I found out in the garage to Fastenal and order some new Grade 8 bolts. I hope I can locate some of the washers, as they look larger in diameter and thicker than standard USS washers. It looks like I saved one bolt and washer for matching up some new ones.
    Do you think that these are consistant between GM makes? I think that Ames has body bolts and washers listed in their full-size catalog. I'll check it out and post what I find out.
    Thanks for the help.

    You can get the bolts from any hardware store. I think the originals are grade 5.
