Hancock52 posted:Pete, have you posted somewhere the position where you drilled or otherwise modified the Lionel kinematic coupler mechanism to shorten the length? I thought that you had but I can't trace it.
I don't have pics now but plan to do at least one more car this weekend. Basically after removing the body and seats I located 4 holes 1/4" inboard of the existing ones. 1/4" will make the kinematic bracket clear the screw heads for the body. If you go with less (greater car gap) you will have to remove some plastic from the bracket. I may still do that on my Challenger cars as the diaphrams are somewhat compressed with 1/4".
The holes are 3mm/.118" from the edge of the frame and are 2mm x .4 thread.
There is a pic above that shows the underside with the original holes and new screw location.
Keep in mind if you do this the springs have to be shortened to compensate. I bought new springs but you can shorten the existing springs. 21" cars come with 25mm springs which I replaced with 20mm. 18" cars like the Power car come with 20mm springs which I replaced with 10mm. About 30 cents each on ebay.
