Replacement cylinder bolts

[bodine465]

Assembling the 787 engine that came with a work-in-progress 96 GTX I picked up. The engine was disassembled when I got it and the cylinder bolts were apparently lost in transition. The engine was being worked on by a friend of the last owner, who returned it in boxes after a falling out.

Looks like my choices are to spend $57 + shipping and wait for them from an online site, buy used ones off eBay and still wait, or look for a local supply house that carries automotive grade bolts. Looks like four are M10 x 75 and the other four are M10 x 105. Does anyone know what the thread pitch is? Anything particular I should make sure the bolts consist of? I know that they'll have to be shouldered for clearance issues, but would hex heads be an appropriate fallback alternative? Any better suggestions?

BTW, I'm also going to need the outer caps for the RAVE valves. Both are missing. Been checking eBay, but they're scarce and overpriced. Planning on stealing the caps off my Skidoo to get by until I find some, but if someone knows where to pick some up, that would be even better.

Fastenal sells botls for just about anything you need, Hex heads would be ok.
Pitch on M10 is 1.50

I recently went through the exact problem, The SD bolts had a shoulder under the flange and the local SD shop did not have any and the ones that did wanted $7 or $8 bucks a bolt that should not cost more than fifty cents.

I went to a local store that only sold nuts and bolts and purchase all 8 for $5.

If you don't have a store locally that peddles the bolts and want a contact, let me know.

You can also try contacting local non Sea Doo shops that do repairs only. That also worked for me.
