LongBox, I missed the idea you promoted and you missed what I posted. I can get Axles from a friends K10 and the year is unknown but it is either late 1970 or early 1980 and the ratio will not be the 4.56 but what is normally under a 1/2 ton.
I'm not afraid of a little 4wd noise I like trucks not cars. Right now I'm running a K30 and that is rougher than a son of a B. Especially here in Maine with the frost heaves.
