Gsi or pb fab crossmember kits?

[Shagggie]

Thanks for the replies,
I am going to run air ride. I already have the pb rear kit but I bought it from someone in Australia who had run out of money to finish there truck. I've seen chopping blocks, pb and gsi kits. pb is a fair bit more expensive compared to Gsi. But unsure on chopping blocks. i am looking for the best value for money kit.

cheers
