Hey Rob, welcome to you and your daughter too, to classicbroncos! Should be a fun project.
And you do realize, don't you, that at 16, it's "her" Bronco now! Right?
Anyway, what they said. And maybe put your city under your name in case any locals might have the stuff you need.
We (Wild Horses) do offer a few kits that might fit your needs too here:
http://www.wildhorses4x4.com/category/bronco_Power_Steering_Kits where the most complete for your particular needs would likely be the #1961 because it includes all the brackets, the hoses and even the lower steering shaft with yokes/joints to match the box at one end and whatever your column ends up being.
For columns, we carry both Ididit and Flaming River, but the one I like the best is our "Direct Fit" series from Ididit. It's the most expensive, but only by a little (once you add most of the other stuff together) and easiest to almost literally drop right in.
They are made to bolt right up with no adapters, still use Ford steering wheels and turn signal switches, and use the more Ford-standard 3/4" x 36 spline lower interface.
So any future replacement items are all Bronco.
The first two in this lineup (#2501 and #2517)
http://www.wildhorses4x4.com/category/Ididit_Columns would be the ones you want to look at.
Bare steel for cost savings, or powder coated black for bang-for-the-buck. If you've ever priced out powder coating locally, then the extra $110 bucks for the already done up one is a bargain.
And you don't have to disassemble your new column to get it done!
But rattle can paint has it's place in the world as well, if budget is more of a concern. It just never lasts as long as factory powder does it seems. However, recoats are pretty much free as long as your daughter gets to drive it now and then!;D
You'll notice that they are not listed for the '68. That's really only due to the wiring connectors included with the kits. Everything else matches up with any Early Bronco, and the wire colors are still Ford, so figuring out your connections is pretty simple.
Depending on where you are, there might be other vendors closer to you. But if you call in to check, we're happy to quote shipping costs right on the phone if you're interested. Shipping is probably not that bad on some of the stuff, but still worth confirming.
Have fun!
Paul
