I've wanted one of those forever- was looking at one on modelroundup.com (Hendrix Manufacturing IIRC) but something looked a little "off", including the price tag . Checked Morgan Automotive Detail's site and didn't see it listed.
If you want the first ones in styrene, they were included in the "Hot Rod" boxed version of the Revell Model A pickup- minus the spinners. http://i.ebayimg.com/images/g/k1IAAOSw241YUt-u/s-l300.jpg That was a dark time for Revell- quality of parts and chrome was pretty bad, but with some clean up might serve as a "roll your own" resin master.
That is a very good-looking 3 window. http://s286.photobucket.com/user/basicxj/media/Little ones/323window.jpg.html?sort=3&o=1 I was going for a similar era with one of my stalled projects using the same rear tire combo, and you are nailing this so far.
Modified re-issue suggestions based on Revell's existing tooling I would love to see: '29 bodied Ford Model A roadster/5 window Stock height '30 Ford Model A 5 window '40 Ford Tudor Sedan '48 Ford Tudor sedan '57 Ford Ranchero any later-model variants of the Dodge Dart/Plymouth Valiant '87 Olds Cutlass RWD '90 (or other model year variants) of the Fox platform Mustang with corrected roof height Station wagon versions of almost any recent tool
Modified re-issue suggestions based on AMT/ERTL/Round 2's existing tooling: '41-48 panel truck based on '41 Ford woody tooling '55-57 (or even '58-'59 variant) Chevrolet or GMC panel truck or Suburban Tahoe or Yukon 2dr based on their late 80's and 90's truck platform Stock or drag (flip front) version of '75-'76 Datsun pickup :no monster truck:
