I too have been looking for one of these.
Start with the big pieces first.
Engine: Ford Motorsports Z460 M-6007-Z460FFT
Trans: 6X SIX SPEED TRANSMISSION PACKAGE; SMALL BLOCK FORD BELLHOUSING & PADDLE SHIFTER
Rear End: 2004 Cobra IRS ; these pop up on ebay from time to time
I would choose Kenny Brown for my chassis strengthening; Subframe connectors, Jacking rails, Matrix brace, Strut tower brace and lower k-member brace.
Front suspension could consist of Stock LCA, 04 ball joint, 94-95 spindles, Baer 14 brake kit
and maybe tri-bar factory wheels
