Great shocks for someone with the SL!
You're better off leaving the gears in. The R&R costs more than the parts and not many shops are willing to install used gears due to noise issues. Id say put an RC lift on it (with the stock parts) and put some 32s on there. Between the plastidip and cut front fenders you're still going to have to appeal to a younger/4x4 enthusiast buyer
