818 CV axle help

[Dave 53]

Sorry for being lazy. I searched a bit, but hoping someone can hand me an answer on a silver platter.

I blew up the wheel side CV joint. Shifting from 4th to 5th gear.

I bought my project from an original owner and the axles are the only thing I haven't touched or know anything about other than I think they are some sort of cobbling together of parts. I recall some shop all the cool kids seemed to be using to build 818 axles. There are several "axle shops" here in the San Francisco Bay Area, but when I call and the first question is, "what is the make and model of your car?", I don't know how to answer.

My CV cups are black (not green). Not sure even where to start on getting these replaced or repaired because I don't even know what I have.

The doner car was a 2002 WRX.
