Initial inspection of A500

Exactly. Published information can't be relied upon. I post what I know from my own experiences. Case in point, your parts catalog only shows the 1.6 band from 88-04 A500, but right above that is a post showing the 1.4 up thru 91. I don't rely on either one.
Precisely why we always asked for the code number stamped on the converter to ensure the customer got the right one. Band wise, I can't say for a fact on the size, and my catalog only shows the one size. It's been a day or two since I was active in the industry and I don't have my old personal catalog that had a ton of my hand written notes. Typically information I got from my rebuilder friends.
