i have sum questions about sum body ideaz i had:

1)where could i find a roof scoop for an xmod.
2)i have colored/clear fiber glass covers, i was wondering if it would be possible to carefully cut out the all black stock windows, then cut a fiber glass piece to the corect size and put those in 4 windows.
3)are the wider rims/tires out there.
4)where could i get brake calipers?(for looks)
