Hello, I am new to the group and have just begun work on my latest find. Looks like it is an all original 57 F100 Custom Cab with the big rear window. Its a slabside short box. I am looking for information about the carb and the air cleaner. There is a one barrel carb and no air cleaner housing. I would like to know what was originally installed on the 272. I've looked around at different sites but could not find anything for sure.
