Cory,
 Thanks for the incredible documentation on the original 5a air cleaner base. I purchased this air filter base from Craig Conley at Paradise wheels, he was one of the recommendations that you gave me when I was looking for this part. Your pictures have definitely confirmed that this is an original part. I have to say, I was a little suspicious when I first received this part because it is so perfect.
 You are responsible for my c5 date correct C4 C servo cover and now this air filter base. Thank you again for your help, you rock!

Hi Karl,

You are welcome for the information and glad to help.  That is what this forum is all about.  On the four base diameter opening's for the carb, I found the below inside dimensions and how well they fit on a Autolite 4100 ZFC carb.

5.05 inch (Repop, will not seat onto the carb.  Possibly an older repop.)
5.08 inch (Repop, barely fits, requires pressure to seat, the radius on the lip opening helps.)
5.10 inch (Repop, fits, but not by much, the radius on the lip opening helps.)
5.15 inch (Original.  Goes on nice.)

The OD for the ZFC carb is 5.10 inches.  This helps explain why the repops are challenged to install.

I hopes this helps others properly ID a correct HiPo lid base.

Take care

Cory

 Thanks again Cory,  next time I go over to my friends machine shop I will borrow an inside micrometer and check my air filter base.
