My radiator is leaking along the top seam. It's plastic. Would it be possible to repair it in some way? Even temporarily? My 93 is my only transportation and I need to get it running again quickly. A friend of a friend has a different year 80 series that they are pulling parts from. I think it's a 91 or 92. Would a radiator from that year be compatible with my truck? Any other years besides 93-94?
