IDK about the lightest but, here's my setup:
465 w/ ORD 32 spline short output
Short (old style) adapter: about 4.5" long
ORD 203/205 Doubler with everything 32 spline
1410 front u-joint at the t-case
rear flange with HAD driveline disc e-brake
Since I went with the short adapter, this whole set up is only about 2" longer than my stock setup (465, long adapter, 208 w/slip yoke). I have yet to drive it with this setup though, we are still assembling the truck!
Hmm, if ya want a lighter setup, ya might could look at an NWF blackbox doubler. IIRC, they use the planetary setup from a 241 in an aluminum case so, that'd be pretty light and be a 2.72:1 reduction.

I'm in the middle of putting one in right now.... I have everything exept the clutch & flywheel and I'm picking up the doubler adapter this weekend. My buddy has one in is 1-ton Scout hybrid and it's a great setup. It's a heavy setup too.... around 400lbs of cast iron between the 465, 203, 205 and adapters, so if weight is your concern, you might want to consider a different approach. However, it's probably the stoutest setup you can find, and is most certainly the least expensive, since everything except the doubler adapter can be found in a junkyard.
My TH400-205 combo was about 3" shorter than the 465, 10spline 203 adapter, 203, doubler adapter and 205, so driveline adjustment will be very minor.

I think anytime you talk 465/205 the weight factor really is moot. Just the size of those two iron behemoths makes the choice of your doubler more about cost and ease of install than weight. So my advice would be go with your wallet, not the scale.
Me too (except more dreaming than thinking at this point )

i do not see where a 465/205 weighs more than a 400/205 combo, remember the 400 is also a heavy guy. I think we would all agree lighter is better on a fullsize.
I have a th400 & a sm465 laying down at the shop if you pick each one up i think ull find the sm465 is bout 50-75lbs heavier than the th400

you could be correct, I just dont remember putting any extra grunt installing my 4 spd in place of a 400.
do any of your 4spd guys think the doubleer is worth the effort?
I have a sm465 w/twin stick 205. it seemed to work really nice, i am planning to add a 203 front on and make it a doubler just for the fact that it would give me just alil longer front d shaft, and having a lower crawl speed im sure wouldnt hurt. Im gona just put my 1 ton axles under and wheel it for the time being and see if i like it the way it is or if i wana doubler.

It is worth it if you can find the parts. I had one in my m715 the gearing was great. As per the weight, don't remember how much it weighed (alot).

For me, the doubler was way worth the effort. I have 4:10 gears with Detroit lockers front and rear, and 38" tall tires. To regear the axles would have been really expensive, and purchasing new lockers would have made it even more so. On the highway, I can cruise at 70 mph at less than 2000 rpm, but when I wanna hit the dirt and climb, I just gear down. I sort of have the best of both worlds! Plus, I increased the front drive shaft length, and decreased the operating angle, which helped out. I'm totally for a doubler...

This is the replacement for my old 45 chevy. Work in progress....
The roof was rusted out so off it came, then I built a crappy cage that I am going to rework.
The truck frame was shortened to a 106" wheel base with the cab pulled back about 6" it is sitting a 4" lift which might be removed infavor 52" springs. rear is a shackle reversal made with 2wd front brackets.
I need to finish plumbing up the brakes and wiring, then I can work on making it nicer.
I am keeping everything off so that I can keep the weight down.

Looks good. i would suggest however that you drill your rear hanger & frame and runs some bolts in there. bolts are stronger then welds. Just my $0.02.

that is already in the works, the truck is not even half finished with what I want it to be.
