$550 is out of budget, so...
i agree with a T-18. but wouldnt you need to find one in a 1980+ J20 with a 6cyl?
given that anything with a t-18 before that would have a d20 behind it.
goodluck finding one, but even if you paid $500 for one, you could sell the T176 for ~250 and you wouldnt be out that much and have better gearing liked you wished.
no j20, it has a long input shaft.
ford or cj t18
kopecki has an interesting formula for building an adapterless np435 dana 300 combo. I think its a dodge trans in a ford case.
...
still longer than a ford or cj t18
...
flems (and I are) right the j series are WAY longer than the cj ones. look here http://www.novak-adapt.com/knowledge/t18_t19.htm
You can't use a pre-1980 cj transmission without an adapter to D300.
Dodge np435 + ford input shaft + $25 pilot bearing + drill + steel works. Search for dodge 435, I think it's in my build thread.
you are forgetting the torque converter. generally, it contributes 2-2.5x torque multiplication. manual transmissions are for losers and weenie motors. a 258 has more power than sharpe's old diesel turd. i still dont see how a transmission swap is cheaper than any other option.

4:1 kit is the way to go and will be the cheapest and easiest route. The kits are like 500-600 depending on what offers the manufactures are running.
Trans swap will cost quite a bit more you have to source the trans, rebuild it, find goofy or hard to find adapters, then on top of all of that you will most likely have to build new driveshafts.
As far as regearing the axles you gonna be hard pressed to do that for 500 by the time you buy both sets of gears, install kits, and new carriers. Plus what size tires are you running 33's? 4.56 would prolly be what gears you would swap to and might be to much for highway cruising. Also you aren't improving your gear ratio by that much.

Who is correct? will a pre 80's jeep t-18 work w/out adapters or not? That seems like a good alternative if i can find one.
well the 4 to 1 kit is around 800 dollars and i believe a tranny swap could be done in the $400 range if i can avoid spendy adapters.
I realize an auto will not necesarily lower my gear ratio but it does seem to allow you to control your rig more (ie. not bounce from rock to rock or stall as easily from riding the breaks). Last weekend i wheeled with two guys who had nearly identical drivetrains except one was running an auto and the other a manual. the guy with the auto did fine while the guy running the manual was in the same boat as me.. ?
Ill do some reading on the dodge np 435.

If i can find a 4 to 1 kit for around 500 than I will most likely go that route but the "advertised" prices i have seen are more like 800.
As far as the trans swap goes, i believe it could be done for under 500 (given i swap in a trans that does not require any expensive adapters). Also I would not rebuild the trans unless I put it in and its not working correctly. Plus, I will be building new driveshafts this summer anyways (when i would do the swap) because im stretching it.
Regearing the axles is pretty much out of the question. Like I said, I really dont care to spend anymore money on 1/2 ton axles.

all the 70's t18 came with a dana 20 so that would still be lower than now but i wouldn't do it. i vote 4-1 kit. thats what i have in my cj. if i would get my injection ironed out it would be great. also are you done with my reamer yet?
