You cannot buy am OEM bushing. Ford never sold just the bushing. You have to buy the whole knuckle from ford racing which comes with all new bushings and a new bearing.

You can buy aftermarket poly and delrin bushings from SuperCoupe or a few people on the M8 boards. I forgot who though. The people making the delrin bushings are copying Doug's design since he was the originator. Even though the knuckles seem expensive they are the easiest and cheaper rout to go when you factor in the time and cost of changing bushings and bearings.
