SM465 clutch question

[K10 KRAWLER]

Hey all, i Just swapped a fuel injected 350 into my truck that used to have an auto behind it, so I got a new clutch kit and it came with both a pilot bearing and a pilot bushing. Which one should i use? I was leaning towards the bushing side of things, just because it would be nasty if some water and mud got into that bearing. but what do you guys think? what should I use?

Front side

Backside

Bushing for the exact reasons you stated

I looked everywhere for a bushing to put into my wheeling truck, but couldn't find one. I'd far rather a bushing just for their longer term durability.
