48bigtrucks,
Thanks! Phoned local parts store, guy looked up Mile Marker and said they had hub that fit 60-68 1/2 tons, but he did not know if it would fit my '64 Burb. Price, $332. and change! I have a shop manual for 1963 and the '64 suppliment. The '63 manual says the front axle is a Spicer 44-5F. I contacted Mile Marker and the guy there wasn't even sure which hub would work. I have been trying to get an answer to my question fot months and have yet to find anyone that can tell me for sure what hub I need. The hubs that are on the truck now are Warn. They work, scarred some. I was hoping to replace them.
