Good luck .
Well, not quite "early"- that's a '67-'72 mount, OP wants the '66 and earlier number referenced above. The later mount is also frequently incorrectly listed as an early mount in many parts listings. In Rock Auto's listings for example, they have the later number listed for '64-'66 Darts, but the correct early mount listed for the same years Valiant/Barracuda... go figure. But then again, they also list 383 and 413 engines as available in the early Darts- I wish! Buyer beware.
