so im in the middle of building my 69 roadrunner and im in the process of putting the rear quarter glass back in but my tracks and all the crank parts are very bent and all the guide wheels (i guess thats what they would be called) are rusted and broke and also missing. but here is my question i have a 70 dart and i was wondering if the rear tracks would fit the roadrunner if anyone knows i would really like to know before i start taking the dart apart even tho it is a parts car or if anyone knows if they make a rebuild kit for the crank and track system thanx

 

I really don't think so they are two different animals, the Dart is an A-body and the runner is a B-body, you might get a guide wheel to work but the tracks I am sure will be different
