I remember being 14 back in 2003 when pops retired from the U.S. Marines he came home with 2 flatbed tow trucks because the Ford Dealership sold him the package deal for $80k which included the 2003 Black/Silver two tone Harley Davidson F-150 & the 2003 Mercury Marauder!!!! Boy waa my High Schools Great & still are as a truck driver because I still drop in every now and then to take them for a spin!
I purchased it and had it sent to mo’s speed shop in Dallas Georgia for an engine rebuild and smaller pulley and I love it. I plan to do a little cruising in 2021
It's a P1SC. A company called Forced Induction Technologies put together that kit. You might be able to find info on the web since the company is now gone. I'd also contact Curless Auto or Mo's Speed Shop as they can both put together and install a kit.
CAR Motorsports used to sell the embroidered items and look up the Mercury Maraudet page on FB. Someone is making them. Mine were made by Colex Customs but I am not sure they are still in business.
At company from KC called F.I.T. Technologies made the kit. Unfortunately they are now out of business but you can still search for a lot of their info online.
