What parts are you looking for?
Body wise;
You can still get the hoods through a number of suppliers. The grill is from the California Special with the running horse removed. The front facia is from the california special also. The rear bumper is from the California Special and Shelby(08). Quarter windows from silver horse racing(unless your parts guy happens to have a set of original FRPP units THANKS MIKE!!!!), wheels it doesn't matter but some guys still have some. Stickers doesn't matter but you can still order them from FRPP dealers or I believe it's through competition graphics who made them originally??

The engine
2008-2012 5.4 is Shelby/GT40 heads, block, roller finger followers, hydraulic lash adjusters, timing chains/tensioners and Shelby cam gears. and the crank is available through FRPP. The TVS is available through Eaton, FRPP, and is standard on the 2013/14 Shelby.
2010 3v 4.6- Stock GT heads with FRPP CNC program, FRPP intake, stock crank and all the other stock items
2012 5.0- Stock GT everything except Mahle Pistons.(and F150 parts)
2013 5.0- Boss 302 heads, and GT/Boss block and crank and all the other stock odds and ends. The Supercharger can be ordered directly from Whipple but also some other dealers carry it. You can order the complete engine from FRPP or have your engine builder order everything also.
The Pushrod stuff isn't going away anytime soon I don't think as the Z304 heads, boss blocks and items are needed outside of Stk/SS.

A lot of this stuff can be bought at FRPP dealers, Ford Dealers and found in Junkyards. The TI sheets also have the factory transmissions covered in the GTs.

Everytime I need anything I just give Mike at BuyFordRacing a call. He has a lot of items that seem hard to come by.
So far I've gotten from mike the Competition kit BIW kit, CJ Recaros, FRPP quarter Louvers, FRPP block off plates, FRPP air bag delete cover.(and 2 sets of Ford GT/Shelby hydraulic lash adjusters for another project) as soon as paint is done I'll be ordering the rear, aeromotive fuel system, block, crank, heads and tensioners. We are talking about wheels now. I've picked up the other items from the local Ford Dealer. There are some other odds and end stuff that I'm getting from Holbrook and Watson racing. All and all, all the parts have been easy to come by. Sure my progress has been very slow since the whole thing is being done when I have the extra time and money. Work has been really busy so I've only gotten maybe 1 or 2 Saturdays a month to work on the car and I'm on a shoe string budget compared to some others running the class. But it's been fun doing all the work myself and with some help of family and friends. We should be out and ready for the 2014 season with the car if I can free up more time and money.
