a couple of top questions?

I have a 69 barracuda convertible and I am in the process of stripping it to the bare bones I just took the trim sticks off where the bottom of the top staples to. In the process I broke four of the bolts is there anyplace that sells these replacement bolts? Also is there anything special that you have to do if you take the plastic tubes off of the top pump? I'm sure it will leak out it's hydraulic fluid should I plug the openings on the pump and the cylinders? I also have to remove the top frame should I take a scribe and mark where the frame bolted to the body? Let me know your thoughts
Thanks
