Distributor Vacuum pod to intake manifold interference issue

I like your thinking, of reindexing dist. cap, I'm 1st wanna exhaust the possibility of incrementing the pump drive gear which should have yielded a 20* change about less than 1/2 the rotation distance of the rotation cap tower to cap tower.
The 90 degree fitting on the vac can seems by far the easiest solution or am I missing something? Is there a reason this won't work for you?
