Many thanks for the input. I've been struggling with this 'problem' off and on for a while and am determined to find a better solution than the 9" dia x 2" high Auto Zone filter.

Maybe there's a difference from car to car or between parts that are supposedly the same.

I think I have everything that Curt C mentioned: 351W / Victor Jr. / MSD 85805 Dist (for Victor Jr.) / K&N (1.25" drop base).

This drop is about as much as the distributor will allow - it puts my element just a little more than 1/4 " (or maybe .300”) higher than Rd's. My ERA has a molded 'glass hood scoop, and a 3" tall element won't even come close to fitting....a 2" element hits inside the hood on the passenger side when closed. I'm thinking if I can distort the base to tilt it down on the right side it may be ok.

I'm thinking that unless I change to a smaller distributor (diameter and / or height) to permit dropping the base more, this is what I'm stuck with.

Bernie Knight - What distributor are you running on your 351W? 'Doesn't look like an MSD....
