Carburetor rebuild kits can be ordered directly from the website here:
https://cliffshighperformance.com/product-category/quadrajet-rebuild-kitsYou can also order by calling the shop directly at 740-397-2921. Phone call volume is heavy so if I don't answer leave a good message and return number and I'll call you back.
IF you order directly from the website make sure to include the carburetor part number. It is stamped on the drivers side of the main casting just above the secondary throttle shaft. Carburetors made thru early 1968 will have a round tag on the same side.
Do NOT use any of the numbers cast into small circles from the back of the casting, those are casting numbers.
Any questions of doubts it is always best to call the shop.......tks.....Cliff
