The 6 speed getrag isn't ideal for your application,the ratios are short and it's weak. Better to for an MTX box if you can.
I am already committed to the 6 speed box as i have it, the mounts are fitted and i have some Dave Mac shafts for it. Just need to sort the clutch and diff. The cars been sat for years before i got my head back into building it and the parts were bought a while ago. If i had the option now i would go MTX.
