[AT] Air filter lookup

[Jim Becker]

What is the inside diameter and how much tolerance is there on the 
dimensions?

Here are a few ancient AC Delco numbers that might help.

A123C - 1-15/16 high, 5-7/8 OD, 1-1/2 ID (fit Volvo 544, P1200, etc.)
A220C - 2 high, 5-1/2 OD, 4 ID (fit '65, '66 Pontiacs with big V8 and 3 
2bbl)
A387C - 1-5/8 high, 5-3/4 OD, 1-5/8 ID bottom, top closed (Triumph TR4)

Of the three, A22C may be the only one available and is easy to find.

O took the air filter out of one of my homemade tractors and said "I'll be 
this is the original from 1983". I think you can imagine how dirty it is. 
There are no numbers on it, and the NAPA guys can't find anything in their 
books. Of course everything is make year model there and they don't deal 
with much small engine stuff anyway. Does anyone have any tricks to find a 
filter than is 6 inches in diameter and 1.75 thick? I'm sure it was a common 
part at the local hardware store back when the tractor was made, but now I'm 
stuck trying to find a replacement with no idea where to look up filters by 
size.
