Rear sway bar link bushing is hard to find!
« Reply #15 on: May 02, 2011, 06:45:53 AM »

It's going to take a little manufacturing/welding, but it is time to simply move on and do a replacement fabrication. The center location of the hole is the important part for handling, but, get a poly bushing with the hole size as the important part. Many of them come with a metal housing on them already, all you have to do is cut a piece of 3/16ths plate steel it can bolt onto (so 1.5 inches wide and 3inches long is about the right size, roughly the size of the metal bushing housing), drill bolt holes to attach the bushing to the plate, then using the original length of the center of the bushing hole to thread start, mark the bent part under the bushing of the original and cut it off at the right length, weld the plate to end and bolt the new bushing on. I't a little bit of work, not difficult, but done properly will look like an upgraded bushing, not a fabricated mess. Paint it black and nobody will know it isn't factory. Need rough pictures, I can draw something up to show it better.

Did Luke ask about me?  I haven't called them in a while.  I will soon though, I need to replace the front shocks in the blue diamond WHICH WERE IMPROPERLY INSTALLED. . .   (SNOTTY!)  and I have to get new sway bar link bushings.  One is missing

He should have a complete link kit though.
Yeah, but they're not the proper diameter and they're only for the front.

This HD front sway bar from the doner 1979 300 is proving to be IMPOSSIBLE to find the right bushing for.  It is 1 1/8" (29mm) in diameter.  All the B-body bushing kits only go up to 15/16" (24mm).  I called a good local suspension shop and inquired about drilling out the bushing center hole.  They said, "We don't like the idea of it - and we've never done it on poly before."  And they have a drill press and I don't - so I don't like the idea of me doing that, either.

Energy DOES have a factory style bushing for a 1 1/8" bar.....but it's for the FMJ Mopars - and their bushings are circular wheras the B-bdy bushings are square w/ a ridge on one end.

I'm about ready to say "Eff it" and do what Dana44 said.  At least I know I can find generic 1 1/8" and 3/4" poly bushings from Energy.

Yeah.  He wanted to know why you skipped town after borrowing $20 from him.  I think he's still pissed.

Another option could be to fill up the corners of the link with a bit of metal, so the round Energy bushing fits.

I wouldn't even know to drill into something like polyurethane.....

Do you use high speed / low speed?  What style bit?  Do you use lubrication or not?  If so....what kind is best?

This would be an expensive part to screw up while learning how to ream an 11/16" hole into a 1 1/8" one properly.  If I end up off by more than 1/32", I've probably just ruined the bushing.

It would have to be cooled somehow. . .  And at a slower speed.  You need it fast enough to it won't bind, but slow enough it won't over heat it.
 
The Polyurathane bushings will probably hold up better when drilling.  I never tried that.

Poly drills like plastic. Get it held solidly so as not to spin and simply drill it, just like teflon, medium speed and not too hard with the pressure because of how soft it is compared to metal.  It has been done and can be done again. If you can find the square size you can do it easily enough without fear, the square sized would help in the clamping procedure, round works best if put in a lathe and spin it to cut rather than clamping it and drilling it. Don't worry about the outside lip of rubber like the original, you could, after removing the bushing, drill the metal housing and thread it, then put the poly bushing in and dimple the bushing about .050inch and intall a set screw with loctite to keep it from moving. Something simple like that. This isn't a difficult customize to work, just time consuming.
