Well everyone I appreciate the help, and now I have a good reference point for the future, but here is the (simplified) follow-up for anyone interested:
The driveway is my aunt's, and she wasnt too keen on forkin over a lot of $$ for this. Also, ditches on the side weren't on the order either, and she needs a space to pull off when two cars come at the same time (too narrow)
So, here was the plan of attack.
I ran down it twice (maybe more) with the BB with rippers down. (First gear, didnt wanna break anything. Havent really ripped before. Plus I aint too good at keeping a straight line) Dropped my piles when they got too big and carried on.
Once that was over, dropped the box and adjusted the right link (manually... have to keep messing with the 3PH to get it to go) (Top link wouldnt move so being a perfectionist was also out, a blessing in disguise)
Set box to just about ground level and hardly touched the lever after that. Grabbed a higher gear (1 High for all you old Ford/NH fans) and ran up and down quite a few times. The the link was adjusted such that it maintained angle and didnt dig deeper, as my box is narrow and the back tires were half over the crown anyway so it worked out.
The drive is now much better and I hope it lasts, but I'm skeptical. Made sure to tell them to "SLOW DOWN" as 30 mph is no good for any non-paved drive.
We shall see.
