it's a kit. fits all autolite 1100's. i bought some other things like hardware that i ended up not using and some 1/2" welch plugs that actually came with the hardware kit... only needed one. the carb was really dirty ended up using napa solvent for a while and vinegar for a while in my ultrasound for days and days to clean it all then an entire can of gumout carb cleaner inside the ports etc. i tore apart the power valve which the website and many autolite 1100 sites said dont do, even the autolite manual said not to tear it apart but it was plugged solid so what did i have to lose. anyway runs like an absolute champ so much more power now that i have the right carb to go with the distributor. Mike's got a great website lots of help and articles and parts galore. I ended up getting two rebuild kits, one hardware kit, and a bag of welch plugs...
