TL: DR

Also, I started shopping for rebuild kits for the rear end since I have that leaking seal, might as well rebuild the whole thing and put an Auburn Select-a-loc diff in it. Anyone rebuild their rear end?
And now if I'm going to be in there doing all of that, maybe change to a 3.55 or maybe even 3.73(but that'll kill my mpg at 70+ crossing the country) I think I'd be pushing almost 2,000 RPM instead of 1700 like the 3.42's.

The only reason I even think about it is because the slightly larger tires and it's a dog off the line until about 4000 RPM...
All that being said, I'm sure I'm overthinking things especially given that once the blower goes on it'll be making a lot more torque and will make the converter seem like it has a higher stall which should alleviate any of that 0-30 sluggishness.

Ashamed these front diffs are glass. I would love to be able to plop a locker in that thing as well. Just like adding a winch down the line, the stuff I do I would likely never need it, but it would be really good to know that I have it if I did.
So I'll likely just wait on the gears as I'll probably be happy with them in the end.





Also starting to look into mounting the trans cooler sort of lower and behind the bumper with a fan on it especially once I have to put the after cooler in front of the condenser and radiator.
If you're 4wd you will need to change the front ring and pinion gears to match also.

I have 4.10s in the 02 mustang and it runs around 2200-2300 rpm at 70 on the highway, but the 4.6 motor makes power higher in the rpms anyway.

the dash cracking is not from the sun, it's just bad plastic period, age and vibration is what does it. I have put epoxy around the center speaker clip mounts in addition to a bottom support to try and prevent more cracking but eventually I will just have to replace it. These dash are not like the old style that would curl and peel from the sun.
The NBS dashes last forever though. I have removed, painted and reinstalled mine twice and it's still strong at nearly 20 years old. Still looks like new.

I really was hoping to get a hoe with a push bar, but at this point I'm glad I didn't. It definitely creates an approach angle issue, and I think I would have had a tough time getting rid of it's looks/function for off-road function.
Down the road I'm looking to build a bumper that'll house a winch nicely without sticking out 1 foot off the front like most seem to.
Finding a bumper for a Hoe is a challenge. I had a bumper kit bookmarked but can’t find it now.

It might not affect your MPG as much as you'd think. Mine has the 3.73 and I get 22-23MPG at 70 and 21-22MPG at 75. Stock 32" tire size. Your 6th gear ratio is .67, my 4th gear is .70.

Yeah I know, I haven't looked recently, but I think my ring and pinion choices were only limited by what's available for the front essentially.

Yeah, all the ones that I've seen are big and or ugly, and way over freaking price.
If I don't build it myself I'll just have my buddy make one out of sheet metal most likely.
Try and keep it high and tight but still have provisions for a winch, front plate, and some tow points.

I mean, I already get garbage for MPG anyway, and around town it is what it is. But if I end up doing 1300-2500mi(each way) a little bit of fuel economy at high speed can go a long way.
I already need to get my new tires rebalanced. They shake like a mofo between 70-80
