so, this is my first ever vintage project, so please be patient with me.... I might have dumb questions and everything is going to be real slow

Actually, I never wanted to own any vintage RC, I used to own Kyoshos, PBs and Yokokos back in the day. I knew it's going to cost a fortune and I will never run them anyway.
But than I saw this picture of a guy selling of his uncle's RC collection in some Facebook group, without being able to provide any details on the items

Did you spot the car in the back? Me too! All I knew it's a Cat, no clue which one. Didn't know the condition it's in, nor what comes with it. But for 20 Euro, I didn't care

And this is what I got







It also came with this 12x3 motor

OK, after spending a few days with Google, all I know is:
It's a ProCat with a Parma body (unfortunately it's damaged in 2 areas, not sure I can save it), slightly dirty and the obvious issues are a cracked top deck and wing mounts. Of course, the first step will be to take it apart, clean it and see what else needs to be replaced.
But from checking for parts, I got totally confused about the wing mounts (and eventually found this forum), as they seem impossible to find, but later models might be a direct fit. Not sure I want to mix parts from several models, but for now that might be ok.
Also, looking for a new top deck might lead me to buying a carbon fibre chassis and top deck. Are there any available that can take Lipos?
Well, that's it for now - I hope someone might be able to tell me where to source parts or what parts might be compatible, that would help me a lot
