My 66 SS Chevelle 283 4 sp Muncie 12 bolt 3.42 posi. I ran into a tree in my Mom's front yard after getting it running, it was raining no head lights and that darn Black Elm tree jumped out in front of me, never did figured out what the previous owner did to mess up the wiring harness, it took me several hours to get it running before hitting the Elm tree, sold it the way it looks in the picture the next day. 1Nimrod
