OK presumming there is no DMD TO7 in the vehicle. The servo could be hacked and just ignore travel limits (let it spin up and down) or go with the traditional elevation with limit tabs. Being a servo it has no clutch gear so it would ruin itself with limit tabs unless you use lockout limit switches... but the elctronics gets more complicated.

About the drive and steering: As tom said above it can not be done easily with the SLU. So I'm supposing independent dual gearboxes are being used instead of the stock differntial transmission, which can be done.
