LS Swap Power Steering - Flow Restrictor

[skyphix]

Hey everyone,
Now that I'm driving my C10 one of the things that I'm noticing is really twitchy and light steering using the LS (hydroboost) power steering pump and my factory power steering box.

From my reading, it seems like I need to use a flow restrictor (rather than shim the pump for lower pressure) - but I can't for the life of me figure out which one of the many flow restrictors on the market will work for my application.

Has anyone else done this? If so, what part did you use?

Thanks
Eric
