Help Needed:
I may have a lead for you on a 57 Ford Custom 4-door Police Car. Last year for the 2007 Knott's Berry Farm Car Show held in April 2007, I borrowed what you are asking for from Steve Pierce. Steve resides in Twentynine Palms, CA. Phone (310) 631-0053. He had two of them at the time, both were used in movies. I'd love to be able to get one for myself, but I'm restricted to only one toy at a time and I won't give up my 57 Custom 300 Tudor. I have no idea how much he'd ask. The one in the picture has a later model FE 390 engine, but it was pretty sick.
Hope this helps.
Bob
