Lug pattern size

What would be the bolt pattern size on a 1980 1/2 ton, long bed Dodge?
I'm looking for a truck for a 16 year old and have come across a few /6, four speeds out there.

Oh, and what kind of gas mileage have you guys seen with these rigs?

Thanks

5X4 1/2 that \6 will get all over the board for MPG but you do a Super Six intake & carb

Back in the day I made a \6 lean the other way in a truck like you're describing

Too much Holiday Cheer!

Two wheel drive has five 1/2x20 studs in a 4 1/2" bolt circle. The 4x4 has 1/2 studs too but five in a 5 1/2 " circle....they eat gas pretty well. I suppose a two wheel drive might get near 20 mpg on highway only.

Thanks for the posts. I was hoping for a little better mileage but I guess with the rearend gearing that it probably has, I should have known. A car would probably be easier on gas.

It's not the rearend gearing as much as the weight of the vehicle.

Put that slant six in a Valiant and it'll get much better mileage than in a 2-ton pickup truck.

On the other hand a pickup is a lot handier.....

72-84 2wd 5x4.5"
85+ 2wd 5x5.5"
72-74 4wd 5x5.5"
75-79 4wd 5x4.5"
80+ 4wd 5x5.5"

This should be in the arcives with the axle ID
