Our new bulkhead fitting for 3rd gen f bodies is complete. This fit in the same holes that the OEM ecu harness passes thru and is great for securing your holley terminator harness when installing. Currently this has 4 versions. A Blank one, 2 version of the single holes a 22mm hole and a 28mm hole. And the 2 hole version which has a 28mm hole and a 18mm holes. The back plates use a recess nylon nut to secure it in place. Zero drilling is required to install this as it bolts to itself through the OEM holes. It printed from a high temp stiff material to ensure it can withstand engine bay temps.
