I have found a set of 3/4 ton axles supposedly out of an 86 K20 truck but dude says that it is a dana 44 HD and FF 14 bolt. Wouldn't an 86 have a 10 bolt and 14 bolt? He also says the front end has no locking hubs. I think the 86 models had the smooth hubs but it seems to me I remember reading somewhere that the number of bolts holding the hub on had a significant impact on doing mods to it. If this is a 44 front then I'm thinking this might be a mixed matched pair of axles being sold as a matched set. The 14 bolt probably came out of an 86 but if it is in fact a 44 it probably came out of a pre 78 truck. What do you guys think? Bottom line- I should be able to swap in locking INTERNAL hubs on an 86 front and be good to go, right?
