Holley 850?
 

I need a base plate re-bushed, it leaks some air so it idles poorly can anyone recommend someone?

call blown 1500 704-574-4020:D

Or buy a new one. I think I paid around 140 or so from Mitchells.

You can even get billet ones so that you don't have to worry about broken ears.

from where Cord?

If your carburetor is a 4 corner idle 850 we offer billet replacements for them. Barry Grant P/N 122244 with standard throttle shafts, or P/N 122226 with thin race style throttle shafts. You can order them through any BG dealer nationwide.

I got an email from a guy says he will replace both shaft bushings for $60 sound like a deal?
