This is amazing.
Did you figure out the F150 tie rods from my old research or on your own? I had every intention of using them on my Bronco but never got around to it.
I have a Ranger M220 now so I'll be regearing it at some point.
I don't remember if it was mentioned earlier or you already knew, but I'm seeing comments that the M190 has a welded ring gear and you'll need a new carrier to regear.
If you do this skip the MT88, it's been having all kinds of issues. Mine sounds like it's full of gravel.
Skip the M5R1, too light duty.
AX15 with Quickdraw adapter is where it's at. I have one going into my 66 Bronco: 2.3EB/AX15/Ecobox/NP205.
Is the stock scissor jack the same as the Bronco one? The bigger tired Broncos have a separate 2" extension that comes with the jack that you could use if so.
Bottle jacks are a solid answer though.
I see multiple sites that say the install kit fits both M190s so my gut says you're good with gears too.
You're definitely trying to do this the right way so I'd like to see you succeed. A tune may be a way to get by but gears + tune is even better.
It does look highly likely the Bronco M190/M220 gears should be a direct swap but I hope you find the confirmation you need. I'm thinking about building a Ranger M220 to put in a 66 Bronco. The width is a good match for a 70s F150 D44. It looks like for about 2k all in I can buy a locked Ranger...
