[QUOTE="Tazza, post: 29505, member: 82"] I made my bushings out of 4140 steel and used a copper hammer to re-install them. Even using a plate as a cushion i can see working too as to not warp one side of the bushing. Alignment of the bosses isn't as hard as you may think. Remember the tapered pins on the arms? they are straight rite? as they don't bind up on the machine, they must be in perfect alignment. Install the un-welded bosses (after removing the old ones) into the bobtach, install the new pins into the arms. This will hold the bosses in perfect alignment, tack multiple places on the bosses, ensure the bobtach still moves freely, then proceed to finish welding them in place. PRESTO, its that easy! the worst part is cutting the old ones out, it was not fun on the two i have done, and i have one more to do *groan*. With my bosses, i cheated and made my own. I have no idea what the local dealer would want for them, but I'd suspect it would be a little steep. I figure mine will be just as good, if not better than the factory ones, nitrided 4140 bushings and pins. The bosses are made out of old chrome bar, with hard bushings pressed/whacked in. When heat treated, the sear surfaces on the 4140 is super hard wearing. It still has a softer core to allow for flexibility. You are doing the rite thing by holding off for the bushings, you should do the job rite and remove all the wear you possibly can, you will be far happier with the results. [/QUOTE]
