Hi All, The new Mopar aftermarket distributor I ordered in from Mancini won't seat into the bushing/gear... The old one (also Mopar aftermarket, just about 12 years old) was tapered. I called them up and confirmed I ordered the one for an LA block. The shafts are the same lengths and the length under the housings is the same. The engagement length of the tapered tooth is approximately .510" vs only .230" on the tooth with the square shoulder. What am I looking at here, exactly? Mislabeled box for some other Mopar application, or did they just cut the shaft wrong on this thing? Thanks for checking this out!
