Cougar KC Rear shock position

[Kevg57]

All

Just building a KC after nigh on 30 years out of the hobby, there is a lot of option for tuning this car but the thing that has got me intrigued is the rear shock position

manual shows building it up in the main part of the manual with shocks at the rear of the car, but it allows for the shocks to be at the front of the rear wishbones as well,

I'm gonna be running the gearbox at position 2 so would there be a best shock position, front or back, and can anyone explain the advantages/dis-advantages of both set-ups,

ta in advance
