Based on what you posted, only 30 series got the synchro 205. This k2500 burb must be a 208 then…if it’s not messed with.
You're right I forgot that one. Well either way it seems to have been messed with. I guess I've never seen an example of auto hubs. Only full time and manual. My 79 full time hubs look just like a moon wheel. Just a chrome dome.

Lol, the theft of ORD's info here is substantial.

I'm surprised at the lack of auto hubs out west. It seems like every 80's GM truck in Ohio originally came with auto hubs. Of course now, of the ones that are still left, they typically have manual hubs because the auto hubs were problematic.
