Looking for various methods and suggestions on the best way to rebuild bobtach holes (where the pins fit) and liftarm pins for a 642b

If the new bushing fits loose in the weldment ( bushing holder) because it is wollowed out , you can buy the weldment and then cut the old one out and weld a new one in , another opition which would be more expensive would be to have a machine shop bore the bobtack then make a bushing that has the same O.D. and the new larger O.D. , a back yard method would be to take the loose fitting OEM bushing and pack JB weld around the gap between the bushing and the bushing holder , or buy a new Bobtach which I priced Friday for a T180 and it was $1,001.00 plus tax ,

It really depends on what gear you have on hand too.
If its the pivot pins where the arms come down and the bobtach joins to, you will need to ream the tapered holes to get it just rite. If the taper is still rite you can buy new pins and bushings for inside the bobtach and you are back to how it left the factory. Now, the point where the tilt ram joins to the bobtach, the best way is to remove the old boss' from the bobtach and build new ones and weld them in. This all depends on the gear you have on hand! Its fairly easy to do with a lathe and a welder, but if you don't have the gear its a bit more complicated, you will need a machine shop to do the work. I don't know if i would trust JB weld though... There is a fair amount of force there.
