Here's what the Explorer 5.0 parts look like. The balancer is too heavy for my 1980 engine, but at least I have a timing cover and sensor setup that will probably work. Gotta pull the old stuff off the engine and start measuring.
Also need to figure out the balancer - either modifying the 2000 50oz (mine's the 28oz style), getting a new one to adapt, or gluing the trigger wheel on my old one.
