What's the deal with rad supports for 80-86 trucks? Looks like there is a repop for gas engines but not IDI. IDI rad supports seem to be still made for the later trucks. Are there really no sources for a new rad support? What is different from the newer trucks? Can the new repops be made to fit an early truck? Mine is getting thing around where it mounts to the frame and the lower parts outside of that. Can probably patch it up if I have to, but have to buy another welder and guard it with my life since I've been targeted apparently just for welders.
