I admittedly don’t have as much experience with the earlier pre 70 1/2 ton hubs but if I had to guess I’d I say your passenger side could have been a 70 Chevy hub as well as Ford(they are all spicer hubs in actuality). The K20 hub dials were red for 1970 and 1970 only so I would assume the K10 would have been the same. The one thing im not sure on is how well the Pre ‘70 and post ‘70 hubs interchange. They must because you’ve got one on the passenger side but I’m not sure exactly what’s involved. I’m sorry I’m not more help on the warn. I think If it were me I’d try and swap to the later ‘70+ style spicer hub like your passenger side has. Maybe even swap in some blue dials to make everything uniform. I’m sure someone else will chime in with suggestions as well.
