no stories?
be very wary of terms like 'prototype' or 'one of xx'.
oft times these are terms to pull a neophyte's eye off of the ball.
if a Shelby doesn't have a -say a Shelby engine- how 'Shelby' is it? might want to check closely on this car.
it IS a prototype of a 65 Shelby with many non 65 Shelby items. some, like the aforementioned items in the cited thread, are basic ersatz replacement parts, others, like say the shifter, are simply incorrect - where lookalike facsimiles could have been substituted and perhaps passed off as 'original' ... or better yet 'prototype'.
there is also no record of this car being equipped the Crager wheels, or 15x6 steels for that matter, so check the safety bead on those rims to see if they are repros.
also be very wary of the 'Registry', for those of us who were here prior to the 'Registry' and contributed to the first edition, know that it is simply a compendium of casually solicited pap. subsequently republished ad nauseum to give an illusion of veracity. 3x5 index cards passed out a COCOA meeting in my case. there was no verification or fact checking. subsequent unattributed 'editing' has been farcical.
Aspenburghound, somebody may well drop serious coin on this car. if it is you, you may be well advised to know, or hire one who knows, Mustangs and specifically 1965 GT-350s in all of their nuance, prior to being relieved of you money. many still yearn for a 'no stories' 65 and encounter crafted salesmanship. good luck.
