Norm,
You pose a good question, but you posted it in the Texas Cobra Club forum. This is really quite flattering since we are the largest & most active branch, but you might be better served to re-post under Cobra talk or to one of the Northeast clubs.
This web site is a generic Cobra web site open to any and all people, manufacturers, real,replica, kits, built, new, used, looking, buying, selling, etc. You will find a wide and varied belief in the different attributes available here, but if you are interested in FFR specifically, you might do another search on the web under Cobra which should lead you to the web site that is FFR specific ( sorry,I don't remember their location-try the NW Cobra Club and/or Factory Five Racing here under Clubs).
Take your time, do a lot of research, compare in person if at all possible, find a local club or group if you can, ask questions, sit in/ride in as many different brands as possible- they are ALL different- then make your choice.
Another good bet is to look at cars for sale- you can find some REALLY nice cars that can be had for less money than you can build one, withthe benefit of instant pleasure.
Good luck- sorry I don't know any source- other than an e-mail to Brent Mills personally.
