Need help on rim availability

Hi guys,

I would like to know if there are any 1/16 scale rims available as an aftermarket because I have a 1/16 1979 Pontiac Firebird Trans Am 10th Anniversary model kit and has started building it a few years back. I am planning to rebuild it back but I've messed up the rims pretty bad.

The rims that came with the model (which I messed up) is the turbo wheels, similar as the ones shown below.

I am looking for either one of the rims below if available.

I would really appreciate it if you guys know where can I source these rims in 1/16 scale. I've searched the internet but none is found. If there are really no 1/16 aftermarket rims available, I might have to build one myself.

Thanks.
