Got mine from a shop in Cottage Grove, Oregon. I'll have to look up the name and contact info if you want to get one. It's a "race shop", I've talked to the guy on the phone and he seems pretty good. He makes the CNC bushing for the MSD's because a lot of folks, like me, need less than the 18 degree's MSD offers.
Grab your wallet, if I remember right it was $40, but I got TWO bushings, so maybe it's only $20 for one? I forget...
Anyway, I NEED two, one for the MSD in the car now and the other for my backup MSD distributor. In case one breaks at a race so I can make a pitt stop and get back on the track.
Found the link to the shop:
