R-33 Shells: E-bay .

TT-02??

Or do you mean TB-02 or TT-01?

R-33 Skylines are Very, Very Hard to come Buy.. I got mine from a friend in Japan..
Tamiya make an R-33 which is Awesome but is rare as..

Mine is a Option#1 R33 Shell from Japan..



I suggest Tracking down a R-34 from HPI or an R-32 from ABC Hobby as they are the only Skylines you can get with ease..
