I have a Ford Autolite 4100 C5SF-A Four-Barrel Carb and spacer for sale. Best I can tell is its from a big block Thunderbird (see below). I had it on a 289 in my Sunbeam Tiger conversion. Was working when I swapped if for an Edelbrock. I would probably rebuild it before installing it anything since its out. $125 obo
