Seat belts are apparently in the mail. They were waiting on a part to ship which I knew when I placed the order. Apparently taking longer than they expected so they asked if I'd be OK with slight change to the order, (almost insignificant) and a 10% refund; they should now show up this week.
Over the last few weeks I've been scratching my head, rounding up parts, taking measurements and notes all to figure out a 14 bolt axle swap and late model disc brakes with internal drum type parking brake. I like good brakes a lot... Also these old 14" drums are nearly non existent, on the other hand modern brake parts can be had now and for years to come.
The 14 bolt GM axle is a very similar but newer 1 ton rear axle that replaced the Eaton in 1973.
See and help with the late model brake discussion in this thread.
