If replacement is the choice, and unless you plan to produce more than 500 rhwp, it's hard to go wrong w/ the FLP 60e

The parts alone would cost you $1000+ to build yours up to that level. Plus the labor and no warranty like you said. The FLP includes some trick stuff your local guy may not want to deal with.

I've seen the 65e in the $2200 price range on GM online sites. Not sure of the 65e torque rating in a truck, but the FLP is probably equal if not better.

One thing to keep in mind is that the FLP is setup for vacuum modulated pressure control.

If you decide to replace, one vote for the FLP.
