A500 strength over the years ?

A500"s in the 4.0L Wranglers, non lockup. Also 88-92 3.9L non lockups. Chrysler stamps a code (831 for example) on the converter. This will tell you what type the converter is and what application it was used for. Also, there are two types of converter hubs, one being what they call a milled flat hub, the other a slotted hub.
