Ls1 power steering pump?

[808turbo]

Hi, did a search for power steering pump conversions and couldn't find a clear answer. Most are doing the 4.8/5.3/6.0 swaps from trucks, I have a ls1 form at 1999 Camaro, and was wondering if the power steering pump was the same as the truck pumps? Also when swapping the fitting on the donor pump do you just swap the big fitting or do you need to swap the piston and spring also?

Thanks
