Troop seat post bolts

[Awesomeness]

Does anyone have accurate dimensions / CAD of the troop seat bolts that hold the upright posts in place (#7 in the picture)? Alternatively, does anyone have one that is functional enough to come apart, that I could borrow/buy, to blueprint and have some made?

My bolts need changing, but are all stuck and rusted so badly that I'm going to have to cut them off. I want to have backups before I do that.

Thanks!

Mine are a bit bent, in the process of re building a lathe, maybe next year I could make some

I can have them made, I just need precision dimensions of one. I would like to have replacements on hand so that I can cut the old ones off, replace the broken seats, and then reinstall the posts with new bolts, all in one day.

I'm a mechanical engineer, so I can create prints for a machine shop to make more, if I can borrow a good disassemblable bolt from someone. I'm happy to post the prints here too, so others can get some made.

I will take some of mine off tomorrow and get some dimensions and pictures here.

The ones I have are made of stainless steel.

Mine aren't... they are steel. Maybe they were made or replaced at some point. Strangely, they are pretty much the only rusty part on my truck, and are totally rusted to the nuts. Since the only way to hold them still is the screwdriver slot, I twisted one of the slots out and then twisted the screwdriver blade on the second one, trying to get them off. That's why the next step is going to be the grinder, but I want to have some replacements [made] first.

hope this helps. stainless.

Is it a metric or imperial thread? 0.313" looks like it's an M8, since the threads typically run a couple thousandths under.

its 5/16" 18 thread. checked with thread gauge, and die. not a high quality part for sure.
