steering gear

I've rebuilt a few and installed the fast ratio worm gear, its a piece of cake. The /6 boxes only used bushings in the sector shaft, so I would recommend firm feel bore the case and install needle bearings. I think they will rebuild your factory worm gear or change to a fast ratio if you want. The fast ratio worm gears really make a difference in the input needed to turn your car, not the best if you have a heavy front end. Being a big block you should already have needle bearings in the sector shaft, and I would stick with your factory worm gear. I used wheel bearing grease and topped it off with gear oil.
