[WPTA] 1500 Spitfire oil pump install

[Tim Prell]

Appreciate the feedback but the problem truly is about this lower unit
housing shifting somehow and not allowing the oil pump rotor shaft to slide
up and into a corresponding fixed collar where the gear below the
distributor sits. I have tried to include better pics to illustrate. I have
pulled the distributor to merely confirm this problem. The rotor shaft
should slide up until almost flush with the top of this housing to meet the
bottom blade of the dizzy gear assembly.

Anyone know how this lower assembly is attached?
