And what kind of "stock" pump is in there now? Since '71's did not come with power steering, it could be the early style with the small metal filler tube and dipstick, or the later plastic style with the larger filler neck. Which one you running?
Agree that the "canned ham" style Saginaw/Delphi pump is the better pump on the market. More tweakable and more performance right out of the box to begin with I'm pretty sure. But if your existing pump is in good shape, it should also work with the hydro-boost just fine.
Even if it's the old style.
But newer is better in most cases.
What size tires are you running by the way?
And thanks for considering our stuff. Appreciate it.
