If you want the easiest installation with no hassles and a quality product, go to LTB Motorsports and Louis will take good care of you.

If you want a robust piece for less than half the price of the SPA unit, try Sweet Manufacturing. Their steel splined unit is NASCAR and SFI approved. They also make an aluminum version as well. Both are collar-type release mechanisms. If I had to pick one word to describe them, it would be SMOOOOOTH. They slide on and off so easily, yet have near zero play.

Really can't go wrong either way.
