Stop in for a cup of coffee

Dual points?

Yep.

But I don't see the part number in the 70 service manual. 2875988

However - that part number on my distributor is between the Hemi 4 speed and auto distributor part numbers listed in the 1970 plymouth service manual. So it must be. It's at least a RB dual point distributor. The vacuum can is reverse direction from the small block...
