I have a good friend who was one of the guys who came to AAR from Shelby. He worked during the fabrication of the cars and then crewed the cars during the series. he still has his "Hot Wheels/AAR" uniforms hanging in my neighbor's (his sister) closet! He has some great stories of the issues they had with the cars during the season and some of the problems they found and fixed on the fly.
I doubt that as the fuel filler is in direct opposition to the SCCA GCR regs, note the "quick-fill" cap on the decklid as opposed to the stock filler dead center in the rear fascia. If I recall (and my mind is well wasted) "safety" upgrades would trump (but not Donald) the stated GCR regulations so a fuel cell would likely have been "OK" and obviously is being filled from above the stock filler location. I do believe the regulations you posted are not the SCCA "GCR"s but an international (i.e. not "Murican" like God intended) version and therefor may vary.
Yes, but under it is the stock Cobra fiberglass trunk tray which is what is seen from underneath. And it was just an alloy tank, not a fuel cell. that was a couple of years off and not in Shelby's budget. Remember in those days a driver was an expendable item, just like tires and brakes!
FYI...those are not the fuel tanks, they are the trunk floor and were fiberglass. The fuel tanks were above them. On the Cobras the fiberglass trunk floors could be off-white gel coat or painted black.
The hardtop AMT modeled is of course neither the "LeMans hardtop" nor the factory option "Berry Plastiglass" unit. It does replicate the top on a touring show car that was shown as the "Queen Cobra". I had a Rod and Custom or one of those period magazines with pictures from an ISCA show with the Cobra featuring the hardtop. I have never found any additional pictures nor what CSX number the car was but pretty sure it was a worm and sector steering chassis.
