Help with body mounting bolts

[mkmc69]

I am looking at a 1972 short bed fleetside that the p/o said has been in storage for more than 15 years. Apparently the body has been taken off of the frame at some point to start a restoration and somehow the body mounting bolts can't be found for whatever reason. I need to know what size of bolts to purchase so that the body can be put back on the frame in order to transport it. I need cab bolts, bed bolts, and core support. Any help is much appreciated, thanks.

Paul,

Are you still selling those bolt kits? If I am looking for a bolt kit for a 1971 K5 Blazer (4x4). Is the kit all inclusive? (IE will I need to buy anything else besides the actual bushings).

Sorry I guess dad didn't word his original post correctly he mean't it to convey the fact that our Blazer body mounting kits include Everything. We sell the Blazer body mounting kits with all bushings, bolts, washers, nuts, and steel bushing spacer sleeves included in them and we sell the the Blazer steel spacer sleeves separate for this kit also but we do not sell the Blazer body mounting bolt kit by its-self. So if you need the bolts, washers & nuts only you'll need to print the above list and visit your local Ace Hdw, Lowes, etc....

Do you guys sell the rubber or ploy bushing kits? I think I am going to go with poly, as I have heard the rubber has a short life (I live in Northern VA--snow, rain, etc).

Either way I am replacing everything on the mounting kit so at a minimum I am interested in the pricing of the steel sleeves.

Thanks for the clarification. (also are the offset washers hard to find)

Radiator Support: 7/16"-13 x 3.375" carriage bolt

Core support bolts, 7/16-14 x 4", carriage head bolt

Is the difference there 67-68 vs 69+?

I know this is an old post,but I had to get core support bolts for my 70 c10 swb,and the bolts are 7/16-14 but all I could find was 3 1/2 long.
They are grade 5 they can be purchased at bolt depot.
$0.70 each shipping was $4.95
Just a note for people looking for the bolts.
