I'm about to go put a later coil box on my car. Nothing wrong with the one I have but I don't have the lid and I spent as much time cramming coils back in as I did driving. 14 lid is hard to find and I bought one, left it laying around and it came up missing. I gotta hurry before dark, I'm ready to go again before dark. Don't know how the picture messed up.
ah, I had to use the old rubber running shoe trick as I drove one day..One shoe on the floor and the other holding the coil down
"One shoe on the floor and the other holding the coil down" Been there done that!
Not cheap but;
This style appears to fairly cheap. Wondering how it would fit your box if you just cut down the tapered bottom edge? Wouldn't 100% correct, but might work and you could keep the correct coil box in place till the proper lid shows up one day.
oops, forgot the photo...
