Split rims have not been manufactured for passenger, light truck or trailer use in many years. In addition to correct assembly of split rims the factor of rust and wear on the retaining ring becomes a huge issue in safety. Given that those rims are 43 years old and likley they have been sitting unused for some time in the restoration process, I would be replacing the rims and tires.
Since this is a 5 month old thread, hopefully you have already done this.
