Anyone have a 3 groove vibration damper their willing to sell? I just finished installing a 300-6 in my wife's 67 shortbed and the engine came with only a 2 groove pulley. The parts book shows a 3 groove for use with power steering and I need one to finish up this project.
Thanks for any help!

I used a two groove on an 85 with power steering. Both belts looped over the fan and crank shiv. One ran an alternator, the other the PS pump.

 

I have the original PS pump mounted already on the stock brackets and I would have to build another set of brackets to get them to line up. I don't want to do that. The original uses a 3/8" wide belt for the alt/water pump and a 1/2" wide belt for the PS pump.
