throttle body bushings

[patrickj]

Good afternoon,I am looking for a re-build kit with bushings for the throttle body on my 85 is there such a kit available and if so does anyone know where they can be purchased ?

There are no bushings to be replaced as the butterfly shaft runs direct in the TB casting.
TB requires machining and bushes installed.
There are companies that do this work on a exchange basis; some offer a free boring out to 52mm at same time
