The Hall and Precision ProFormance kits appear to be the same. Hall makes nothing in-house and since Bob and Don both worked for Hall at one point, they know the sources for most of the Hall products.
My Pantera has a Hall Pantera aftermarket front hood latch kit. Recently, the latch became very hard to release so I set out to get a new one. I called Tara at Hall and not only did she not have any, she had no idea what the OEM application was. She had drawings, instructions, parts and sources listed; everything except the OEM application and source for the latch itself. I called Don and explained the situation. As expected, he knew exactly what the OEM application was!
