Slant 6 timing cover

I have some extras for you as well. I am not sure when the crossover point for the timing covers went from Bolt on -1960-1966 or so and spot welded onto the Right side of the timing cover. - ~1967 to 1987.

But I sure Have a bunch of the spot-welded ones that I could clean up and sell ya!

Sometimes the engine has been swapped, so even though you have a 1975 duster it could have one of those bolt-on timing tabs from 1960-'66 with a matching harmonic dampener and timing cover.

If charrlie does not have one (unlikely) I can help you out.

Best of luck!
