Wow.. I'm not sure why everyone thinks these aren't available. (I didn't notice when that thread was dated). Dodge had them, Summit has them, Moparpartsgiant has them, and Rock Auto has them..Just Google up Mopar 4294639. (I got 4 from Dodge, next day, for $32.16). Ordering from online sources.. you'd wait a week, and $5 to $7 each plus ? $10 shipping and it's $35 + anyway (for 4).. so why wait.. Call local Dodge.. Having said that, I'm also sure the ones this guy made are much better than the stock ones, so... I would have bought them from him. But another personal observation. These things are so thin that even Delrin is still going to wear out, (especially the left one where the clutch is being pushed 4 times more than the brake), so ideally, If I had the bracket out, I make new ones from Silicone bronze. In fact McMaster Carr has flanged bushings, some with 'channels' for graphite grease, and I'd try to find some of those and modify if necessary. (probably too thin to have channels, but I'd look). I think I may have lucked out, and only my left bushing is missing, so I'll be working to get that new one in today.. but winter is here.. and it's cold..
And, just for clarification, I'm pretty sure, Auto trans, (w/ one brake pedal), requires 4 bushings and Manual trans, (w/ two pedals), needs 6 bushings.
