I have done the backdating of my 69 road runner to a 68. The trunk tail panel was cut from the amt body along with the tail light housings. One other thing is the side marker lights on the amt are recessed into the body. Those lights are supposed to mount flush on the body.

Well look up the specs. It list Plymouth "B" body 116 inch, Dodge "B" body 117 inch wheelbase. Same on Cuda and Challengers had the longer wheelbase. The one inch difference between a road runner and a super bee is sixty-five pounds. I suspect that AMT used the 70 Coronet chassis for the 68 road runner and 69 GTX. MPC made the Dodge promos and Johan made the Plymouth promos. Compare a 70 Coronet promo or the kit, with a 70 johan GTX promo and the Plymouth is a shorter wheelbase. The AMT chassis is too long for a Johan body. Same thing on the Cuda and Challenger. The Plymouth line was always lighter than the Dodge, that's why the racers majority preferred the Plymouth. I've measured the AMT body and when they added that inch in wheelbase and top, they added another scale inch at the end of the quarter panel. They tried to make it look right but couldn't. Another thing they got wrong was the flat tail panel on the trunk. That tail panel is supposed to have a vertical peak in the center and the rear bumper peaks in the center to match the tail panel peak. The Dodges had a flat tail panel and bumper. Now I am glad to have the 68 road runner but only cause it has most of the body parts that can make a Johan 69 road runner into a 68. One more thing is that the radio is wrong on the AMT. All road runners, GTX's, had thumb wheels and not knobs. The side marker lights are not recessed into the body on a 68 they are flush mounted on the body. I don't claim to know it all but I bought a white 69 road runner and that was stolen and burned in 1976. Loved that car. The 68 road runner 426 was the fastest production car in Chrysler's lineup running 13.55 quarter mile times, period.

Ì would move it to the pickup section, if I knew how

No I think they came from the Baldwin Motion corvette kit (Revell )

This started as a 72 "GMC" but the front clip was exchanged for a Chevrolet clip. It is painted with black lacquer and airbrushed flames. There is two Harley panhead motors and photo reduced Harley oil case boxes in the bed. I built this in the early nineties and won best truck and best finish at an AMT model show at a Houston Autorama

I had to add my thoughts on the amt 69 GTX, 68 road runner kits. The main problem I see with these kits is that the wheelbase is wrong. The 68 trunk tail panel should have a vertical peak in the center. The side marker lights are recessed but should be flush. Amt obviously used their 70 dodge chassis 117 inch, instead of a Plymouth 116 inch wheelbase. The real 68 road runners were one inch shorter on wheelbase than dodge cars and was 65 pounds lighter than a dodge. It is much easier to backdate a 69 Johan GTX or road runner to 68 by removing the tail light housings and trunk tail panel from the amt body and redo the side markers flush. The trunk tail panel has to be bent vertically in the center with a scribed line on the backside. The amt guys, should have shortened the dodge chassis but they added another scale inch to the end of the quarter panel but when they did that they omitted the vertical peak in the trunk tail panel and the peaked rear bumper, to keep the overall body length measurement within spec. I have back dated a 69 Johan road runner to 68 road runner using amt’s 68 parts, hood, grill, interior( that has to be narrowed 1/8th inch). I just joined the forum and would post pics of my conversion if I knew how. Don’t get me wrong I’m glad amt released these kits if only for the body parts to use on the Johan body for a 68 conversion.
