I will be going to New Ulm in the next week, and will stop by the fellow who gave me this tip. Will let you know what I find out.(shhh)
The cortex silver sounds interesting, do you know more about it?
I have recently seen a column shift '69 with blue interior, but painted black, original color was glacier blue, has Harrell emblems on the back 1/4's like Kevins. X44 code, now has a pass. '69 427/335 with T400 in it. I will post the VIN (with permission from current owner), as he is trying to determine if it is a Harrell car, transplant vs tuner. It is not a Gibb car. Car has not been touched since early '80's, does run with 75K on odometer. Apparently was from Florida in the late 70's. Stored since, however, now back on the road.
