1968 Ford Mustang - skooli

I bought this car in 2003 and have been slowly getting it where I want it to be. I replaced the tired 302 with a 351w with Edelbrock RPM heads, a cam from CamMotion, and a Holley 650. I traded out the BW T-10 for a Tremek TKO 5 speed. The rear suspension now has 5 leaf mid eye leaf springs with Shelby under ride traction bars, KYB gas shocks and a set of subframe connectors. The front has 620 coils and new control arms. I swapped out the original drum brakes for a set of discs up front. And finished it off with polished TT-IIs. I retire from the military in a couple of years and plan to go full pro touring. I would like to swap in either a TCP suspension or a Gateway Classic suspension like thier 68 track car has. I want to mini tub the rear and drop in a new 5.0 Coyote engine.
