A couple questions on 62 power steering conversion

[HotRodx]

Ok just to start off, I used the search feature on the forum to already answer most of my questions with this topic. I only have a couple left hoping to get resolved.

Just bought a 62 c10 stepside with a 396. The steering box was missing and I thought great time for power steering upgrade.

I already ordered the 60-62 CPP conversion box brackets (which is only $55 on ebay right now instead of the usual $95, by the way)

First, specifically what application do most guys use for the steering box? I know CCP specifies 69-87 2wd, but I see there are different generations of boxes in there. I see different listings for 68-76 ; 77-79 ; 80-86. I assume the changes from year to year are going to include the usage of o-ring fittings instead of flares, but I didn't know if there was a more desirable ratio-box in there or what.

Second question, is what do you use for the pittman arm? Stock 62, or is there a specific model 69-87 c10 that uses the right length and angle arm? Mine is missing so I have nothing to mock/compare setup

And lastly, before I go digging on Rock Auto all night looking at specs and pictures of high pressure hoses, is there one that is standard to use for these trucks? I know I can always just make my own with black AN hose, but I rather just get a $15 stock appearing one

Thanks for any help
