1. Is the 3 speed worth keeping, I have 3.50 gears, so if I am driving 65 ill be humming along at 3000 rpms (I had her up to 50 today, and that me a bit nervous), I'm not so sure I'd want her up to 65.....
This thing will mainly be on pavement and gravel roads, I don't plan for any super long road trips in it.
It's a good little transmission, if you can ignore the fact that it's got pretty crappy gear ratios for happy truckin' on the street with larger tires.
With no long trips planned though, it's hard to justify a new transmission with overdrive. At last for the short term.
But you are saying it's yours for the long haul it sounds like. So in that case, a different transmission could be totally called for, if just for added fun while driving around town.
Better gearing equals more smiles.
Once it's dialed in, you should be able to cruise at much higher speeds. I never thought twice about going 75 or 80 for short bursts, and 70 all day long (relatively speaking).
Never even occurred to me that it was anything but safe and secure. So it sounds like there are plenty of other things to deal with right now, but in the end you should be able to drive it any where, any time.
2. I have a list of things to do, one of them is getting the turn signals working. I am debating ordering an entire harness and wiring the entire vehicle. Knowing that I will be rebuilding it in about 10 years, Is it worth it to do that now?
3. I plan to replace the steering column with a tilt unit, I'm lanky and the extra adjustment would be great. Again, considering I will be doing a full frame off in the future, is it a waste to go ahead and install a new column now?
Yes, and no.
What is the general condition of the wiring overall? If the only thing acting up right now are the turn signals, it might be a simple and quick fix that costs 30 bucks in parts.
If that's the case, then it's totally worth waiting.
If you start to find other things, such as the steering column needs a total rebuild, then you're better off getting the tilt column now, which will come with a new turn signal switch and all the wires.
The good news is that the column wiring is completely independent of the rest of the harness, so you can go either way and not make a bad decision.
The replacement harness is a lot of work. But it's totally worth it for peace of mind and having everything work as expected. If you start messing with wires and find that their outer jackets are just dried out and splitting when you try to move the wires, then in my opinion that moves the new harness install up to near the top of the list.
I'm struggling a little bit with spending a bunch of money on little stuff now (turn signal guts, pig tails, etc) knowing it will all be replaced later, so maybe I should just do it now.
That's not the wrong decision in almost any case. But it's all about how long before you do those other things.
Frankly, most modern replacement parts are lucky to make it ten years in the real world. So you might just wear out another turn signal switch while you're waiting. And then you can install the new harness and the new switch the next time around.
But the argument for doing it any time, and even after buying other new parts that might get tossed, is that you don't have to toss the parts.
There are so many people doing full restorations, many from literally a Bronco-in-boxes, that there is a demand for used parts. So you can literally re-sell your rebuilt steering column with new switch to someone who's struggling to get their rebuild done, give someone a good deal on a hard to find part, while making a little money on the side getting rid of your old stuff.
It's like putting in a new ring-&-pinion gear set now to get a good ratio, then deciding later to buy a whole new 3rd member with new gears and a locker and a new housing. Some of that money can easily come back when you put the new parts in, because someone is always looking for a good used rear end to put in their project.
So some of the negatives can be overcome.
I know that just makes your decisions harder instead of easier, but at least you know the results won't always be painful!
