I was looking up gear sets and found a place that carries a lot of them. BUT, I don't know what size the rearend in a 76 luv 2wd is. HELP!

As in you just want order a ring and pinion?

yessir!

10310 was asking the same question, I told him to just buy a whole third member because that costs the same as a ring and pinion, and used third members are readily available in any of the following ratios;

4.56, 4.10, 3.90, 3.73, 3.42.

That is unless you like setting up differentials; I chose to go the third member route because I didn't want to bother setting up pinion preload, backlash, and tooth patterning. I've done that to a Chevy rear end but never to the third member style rear end. In the Chevy the rear end remains in the car and you use the axle as a test fixture rather than trying to clamp the thing in the vice like you have to for the third member.

I want the lowest possible. Which ones carry the 3.42? I search, but so much comes up I start to get confused...

The lowest one would be the 4.56
Do you want torque Or top speed.

Sorry, I want gas mileage

I suck at gear ratios....

You gotta go with an Isuzu Pup rearend for the 3.42. Pup diesels. I think Pups up to the mid 80s will work...I have an 83 Pup rear in the 3.73 ratio, it fits.

Cool! I hope I can find one! Thank you!

Thanks for the ratio information, I have a 3:42 rear end in my formerly diesel powered 81 Luv but it is not a posi traction, does anyone know if a locker rear end was available in either the Luvs or Pups, and when. The 3:42 works out beautifully with a 700R4 OD transmission back of a slightly warmed up 305, great gas mileage, slow rpms at 65!
scjconv

there are two ways of telling if a puppy has 3.42 gears
they will say MPG+ on the rear of the cab, behind the doors, at the top of the bed rail hight. letters "about" 1 to 3" high

the other way and its not 100% of the time is they have a 4 speed not a 5 speed, unless it was sold in CA state.
then for some odd reson its a 5 speed

also if a gasser has a 4 speed, i think its a 3.42 as well, but im not 100% on that.
a 3.73 will be much easyer to find sence there most commen
HO yea theres the auto trans puppys there all 4.11s
ive yet to find a 3.90 gear in any pup, mabe its a pre 1981 LUV thing

do you live in a hilly area? or have a drive way that you stop at the top to look for traffic or move lots of cargoLBs if so you will like the 3.73 better.




P.S.
if you find a pup that still has the diesel trans, that trans / bell err frunt half of trans case, is very hard to find.
the starter is on the other side of a gas engine.
thus to change a LUV\PUP to diesel you need a engine and bell housing not just a engine
you may find a buyer for it.

if you where close to me i whould give $60 in a hart beat to get one and thats just the bell.
