I don't know if anyone else has had an issue, but the stainless collet hardware that Banks uses created some issues when I recently put my truck back together. Two of the stainless nuts cross threaded on the studs, one on the turbo mounting flange and another on the bracket that secures the downpipe to the manifold. The EGT probe also fought me coming out and I ended up drilling and tapping that as well. I called Banks to purchase replacement hardware and got a quote of $70~ for a couple studs and replacent nuts. Banks still supports their stuff but if you try and stick with parts sourced from them your going to open your wallet and dig deep.
I ended up finding what I needed at Home Depot for about $10; however, they didn't have it in stock and I ordered it online. There's a parts sheet in the instruction manual so you can ensure you're getting the original thread sizes, those studs had two different thread sizes on each end. While bolts might work, the risk of stripping the threads out of the cast components was too daring for me so I waited a week to get the right hardware.
All in all, it was easy to remove and replace, just expect that you may have to buy a tap and some hardware depending on the condition of the current fasenters.
For tools, I found a swivel and a crowfoot wrench set that attaches to an extension to be invaluable. Along with a flexible stick magnet if you accidently drop anything between the engine and firewall you should be able to get the project done relatively quickly. I used high-temp anti-sieze to reinstall so I hopefully don't have hardware issues if I ever need to remove it again.
Edit: Banks gasket kits are available on the cheap from Amazon or similar vendors. It had a new oil tube to turbo gasket, oil tube to valley pan gasket, and intake gasket included with a couple other things.
