#6 Plug Wire Clearance Help

Installing a set of MSD 8.5MM Super Conductor ignition wires on my 440 swapped 1970 Duster

With headers, clearance is slim.........

I was able to get 7 wire boots snapped on the plugs, however the #6 cylinder plug is giving me a VERY hard time

I really don't want to massage the inner fenders at all

Any tips or tricks?
