Call us to place an order to get the right parts for YOUR setup and accurate shipping costs: 740-397-2921

In addition to kits, we sell many other parts, including choke pull-offs that have been discontinued. We stock Pontiac Ram Air pull-offs with two fittings, the 73-74 Pontiac pull-offs, and the discontinued 71-72 Pontiac/Cadillac/Buick pull-offs. We have the linkage from the pull-off to the secondary air flaps & several fuel filter housings.
