I'm not exactly suggesting you buy it. Just for reference. You may be able to find something less expensive. I've never dealt with them, but many on here seem very pleased with help they got from Brewer's Performance. You might give them a call.
Honestly appreciate the insight. Called around to my local old-school shops, and didn’t have any luck. Was crossing my fingers that someone had one in the back room or something. No luck.
I ordered the bushing off of eBay. Crazy—now that I know what the problem is, I see countless threads on the issue. Thanks again for the help.
