spazdog has good idea. case in point in 1967 i bought a 1965 Chrysler 300 L. the amp gauge in the dash had all the current going through it. but they did not make the fiberglass panel beefy enough, so had to rig up a mickey mouse fix. also the same year was the first year for a new ball joints. they was easy to install, but cost two times as much as the old ones, but the old ones are VERY hard to put in. if they could mix the two, that would be good. i could go on, but you get what i mean
