2002 Z28 Convertible

Front tires: 285/17/40
Rear tires: 315/17/35

Corvette brakes on all fours. Huge calipers on front, slightly bigger rears.

Problem: original spare will not fit on the front and I doubt it'll fit on the backs.

The rims I have are corvette branded rims(?). They're in the pic listed below:

There are other pics you can look through to get an idea of what they look like. However, I cant find em online for anything. I'm thinking they're not sold anymore.

So heres what I need. A spare rim. I'm pretty sure I can get 285/17 rim and just put a 35 height tire on it and it'll work til I can get my flat tire fixed.

Opinions?
