On bushing the primary throttle shafts, I used to take well worn Qjet throttle body's to a local carb shop that charged $40 to properly bush the front holes and reassemble. Then a circle track builder buddy from the same part of the city, bought a kit out of AZ alongvwith a small bag of bushings to properly rebush the throttle body's, and we repaired a few early together. Both of those sources are now a 30+ min drive, and I can guarantee have gone up in price (or price of favors). Recently found a local shop through chatting with an exPontiac buddy who owns the NAPA two miles from my home to bush the primary throttle shafts. Am going to try him out soon, as the price is really good and the shop is less than 5 miles away, near one of my favorite Mexican restaraunts.
On the 7/8" inlet (early style) Qjet's, I finally broke down two years ago and bought a repair kit with quite a few stainless helicoils. Found it on Amazon. There are several sources now. Have used it twice at another buddys shop, he has a Bridgeport. FWIW, about 5 years ago, the elder Carb guru on the big Pontiac board, gave me a part number and a place to order the helicoil installation tool from....just the tool was over $350. Glad I held out, a few years later.
