My 85 lifted full size bronco with 33's turns on a dime. Should help with positioning a plow in tight spaces. I'm still amazed to this day how tight the turning ratio is. Never seen anything like it. Came factory with a holly on it. Said made for Motorcraft by holley. Like a 6150 or something like that. Mines a 9" drop out rear with bad bearings in diff I think and a bad fuel pump.
