This will be an ongoing project. I've been compiling a list of hardware as I have been freshening up 3 late B230s in the shop. More to come. Open to suggestions on how to present this info in a better way. If I ever get a computer in the shop, I have considered posting pics of the part and bolt along with the dimensional info.
