restoring a hotshot

[qatmix]

I've recently got ahold of a hotshot, It needs a lot of time on restoring it thankks to eh scres being the wrong size etc. Its also got a broken connector on the rear Suspension ( Its part no R-4, of the R-parts tree)

Does anyone have any hints and tips on how to get the best out of a hotshot? Its going to be a car that gets ran around the garden / park. Bit any tips on sorting out the bumpsteer etc will be appreciated.

Also if anyone has a spare R-4 part and maybe a 15t tamiya hotshot pinion please let me know.
