Alright guys, thanks to some members, I'm back in the game with a new project (s).

I purchased a 1970 Sport, nearly all original, that will be getting restored, mostly to factory. It has the Dana 30 front and small bearing limited slip (code A3) rear that came with the truck. I have access to a ΓÇÖ76 big bearing axle (code 03J) from my other Bronco. Both the ΓÇÖ70 and ΓÇÖ76 axles are 2780lbs, according to the VIN decoder online, though the gross for the ΓÇÖ70 is 3900lbs, while the gross for the ΓÇÖ76 is 4900lbs.

Here is the question. In my line of work, you donΓÇÖt take an all-original vehicle and modify it if you can help it. After balancing resale, originality, and usability, do you think IΓÇÖd be hurting the truck to swap in a Dana 44 with discs, the ΓÇÖ76 big bearing rear, 2.5ΓÇ¥ lift, 23 gallon tank, and an NV3550 transmission? In addition, with 31-32ΓÇ¥ tires, can I leave out a power steering kit, or will that hinder me when I get on a trail?

My gut tells me to do the swaps (without power steering), but figured IΓÇÖd get some input from those who know better. The most aggressive trail I can imagine driving is Kingston Peak trail near the top of St MaryΓÇÖs Glacier (the same trail that overlooks Loch Lomond near the ChinnΓÇÖs Lake area ). It has one really rocky section that takes throttle control, but nothing . For the most part, this will be a camping truck.

Thanks for any input.

that 76 looks familiar......

Sure does, once things settle down I will find another.

The '76 is a good truck. Think I found the build sheet in the rear springs, but won't know without pulling some bolts. It will be sold once I decide what to do with the Sport. I hadn't planned on selling the '76, but the right deal came at the right time on the '70, so I'll have no choice.

All depends what you want. Are you concerned with resale? Stock restoration/restomod?

If your not going for a stock restoration personally I wouldn't worry about it.

If you found the build sheet for the '76 it would be interesting to know the original color since Marti couldn't provide it.

I don't think swapping axles will matter much and I wouldn't hesitate to add power steering, you will want it on the trail. I would probably add power brakes to the list eventually as well.

If your not doing a factory restore and going for a "driver" the more friendly you make it to the common folk the more it will fetch. Just my two cents.

Thanks, guys. You pretty much confirmed my thoughts.

I took a break from work and popped the "build sheet" out of the springs on the '76. If it was a build sheet, it WAS a build sheet. Not much left, and no legible writing or markings.

Guess I'll get to swapping the rear ends when time allows. Thanks again for your opinions, guys.

I don't think making changes mechanically that don't change the look of the Bronco will have any affect. The resto-Mod is super popular (think ICON). Adding a 44, disk brakes, power steering, etc. would only be noticed by purists. Adding 11 leaf springs, progressive coils and the like fall into the same category, it allows the consumer to enjoy the product better.

I'm sure you see it all the time in your shop. Folks want some nice "upgrades" without taking away the spirit of the vehicle.

All that said, I would love to come watch you work on the Bronco just to learn from someone who does awesome work. :) Even being just a fly on the wall would make me regret some of the work I've done on my own I'm sure.

In agreement with the others and the mods you speak can be reversed if there was ever a need. If I were to have a second cruiser bronco, I'd go as far as EFI, good tranny, power brakes and steering and modern suspension springs.
