Holley baseplate bushing kit
 

Hi. A buddy of mine has a Holley that is leaking around the throttle shafts. I remember seeing a throttle shaft bushing kit a couple of years ago that came with bushings and drill bit. Anybody know if these are still made and who carries them? Thank you.

Try this link but the kit isn't cheap.

I think that Goodson still has these kits too. The biggest problem is that the throttle shaft wears as much or more than the baseplate. You can get new throttle shafts but sometimes your best bet is to just get a new baseplate Assembly from Proform.
