Test Fit Firewall Recess. Tight fit, but it eventually went into place.
Drilled last two 3/32 holes in both F-601P Spacers. Had to remake one since the first one rotated when I was backdrilling.
Next: - Drill 3/16 holes in both WD-602 Upper Engine Mounts - Fabricate and match drill F-601Z Aux Fuel Pump Firewall Doubler - Deburr everything - Dimple and C/S as required.
