Sliding Contact (Clock Spring) Part Numbers

I am wanting to replace this, but need to order a new one first. I know there are first gen and second gen air bags for these cars, but I don't know if the different parts are compatible.

I also know that the part number describing the actual piece is 14A664.

I mention the compatibility because I have found part numbers for later cars, for example: F7ZZ-14A664-AA, F4ZB-14A664-AA, etc.

I need one for a 1993 Mustang but am unsure whether or not I need to order one for my specific year or what other part numbers will do.

Any help is greatly appreciated!

Bump. No help with this? I found F3ZZ-14A664-A for a '93 Aerostar, which indicated a '93 part and the first Z mean Mustang or general use. Should I be going to Ford with this part number?
