Does anyone know the bolt sizes for the radiator shroud cover, The plastic cow for the windshield wipers, The Trim that goes below the grill fastener size in the trim pieces that attach, Lmc they have the fasteners They don't tell you what size? Any help would be appreciated finally getting my 2500 back on the road in doing a basic restoration

 

Do you have any of those fasteners? I am hopeful you have a few and did not toss all of them. If so, find a fastener dealer in your area, probably in your industrial area, and you can buy thread pitch/size measurement tools on a cable. One for each size fastener. You can buy metric and standard. Not terribly expensive. They pay for themselves many times over if you work a lot on cars and motorcycles. They have a female end and male end. You screw it into a nut or hole or screw the fastener into the female end to find what you have. So if you can access the holes you can easily use the male end of these tools. And then you can proceed to buy your fasteners at the fastener dealer and pay less money for them than at LMC or other sellers. Here is what I am talking about:

 

Take a bolt out from somewhere else on the truck one at a time until you find one that fits. Take that to the store with you. Auto parts stores sell bolts. Home Depot sells bolts.
