Default Need Help Gearing a TC3 to run a 17.5brushless

I've recently stared running cars at my local hobby shop. They run a vintage trans am class with 17.5 brushless motors on 6cell nimh. I bought a used TC3and need help with the gearing. The gearing charts say the optimal gearing is 3.5:1. The closet I can get is a 69Tspur with a 49T pinion. There is no way that gearing combination will fit in the chassis. Can anyone help me out?

Or go 64 pitch and Dremel out some of the webbing in the chassis for pinion clearance.
