Yeah, well I go back just shy of 50 years doing this full time and I remember getting them out and saving them or at least most of them, but older trucks that are run here in the northeast, and especially double frame trucks can be really stuck. But shop labor worth a lot of money anymore, so I just figure on buying new bolts if I have to do one. I'm up in Hazleton Pa and when you remove a mack trunnion in a double frame truck, bolts are usually the least of your worries, the damn rust jacking is your big worry.

Those are all "body bound bolts" They have a shank that is larger than the threads. When you install them you ream the hole to tightly fit the shank of the bolt. That way the bolt also acts like a dowl pin. They don't come out easy. You are not going to spin the bolts. You have to spin the nuts off and then drive them out. Most times they get damaged while being driven out. When you get new bolts the shank diameter and shank length are important. There are larger diameter shanks available because if you are swapping parts around you will need to ream the holes oversized and instal the larger OD bolts. Being you are using the same parts on the same frame rails, you won't have to ream the holes unless something gets damaged. I swear I met you. Did you stop around Eugene Evans shop with Tom Zacny? Or maybe with Thackray or Joe Capecci?

Nice truck. Where is it located? The barn on 611 & Street Rd?
