I guess that would be the same as asking, what are the dimentions, OD and ID of the bush and the flange dimentions ??? ,,,, and what about the insertion depth, and thickness of the flange itself ???

I suspect that a through the mast bolt would benifit significently, if it's down load was spread with a larger than the bolt, diameter bushing surrounding it .

Also, if the mast through bolt is ss , would an aluminum bushing be appropriate, or would a ss bushing be more desireable ???

Hi Douglas,

If it's simple like a shroud tang or spreader base I suggest you consider a compression tube. Much easier to make and prevents overtightening. Simple S/S pipe has worked for me in the past.
If you require load spreading, consider aluminum doubler plates fastened permenantly and the compression tube.
If the bushing can stay put (not usually removed) I would go with S/S same as the bolt and TefGel the bolt to make the bolt much easier to remove years later.
