I'm picking up a spare throttle body for my '85 2M4.

I would like to send it out to be re-manufactured. (including re-bushing it)

Any suggestions for a reputable place?

Thanks!

I can't speak about rebushing but I have rebuilt one using new gaskets and o-rings from an Advance Auto kit. Costs about $34 and included all the gaskets and o-rings needed. Fixed me right up.

I got a GP Sorenson from Autozone that I used to fix up my Holley. IIRC it cost me $15. It had the fuel meter gaskets, regulator diaphragm, injector O-rings and filter, and inlet/outlet nozzle gaskets.

The regulator diaphragm, nozzle gaskets, injector filter and O-rings fit the Holley. I dont recommend you open up the top because there are no gaskets that go on the fuel cover and you will need to Frankenstein a new one. If anything change the regulator diaphragm, especially if its been sitting without fuel in it for an extended period of time. It does get rusty and the spring loses tension.

What is this "rebushing"?

Rebushing is for when the TB wears out from being opened and closed a large number of times. The throttle shaft actually wears away the bushing surfaces, and ends up fitting loose, allowing vacuum leaks.

I am not currently aware of anyone performing this type of repair service on these lowly model 300 TBs. Perhaps a call in the yellow pages to a local carb shop could get you some better results.
