Hey all, chipping away at getting my Dad's old '54 3100 back on the road. Making some progress... I just ran into this. I pulled off the wheels and was kind of startled. Before he passed, he told me he had mounted up some old Ford Mustang wheels to the truck and had used adapters to put on the 5x4.5 wheels. He remembrance was off; rears were mounted via adapters (he had put in a positrac rear 10 bolt out of an old '57 BelAir) but the front was done differently. He bolted the drum to the hub, and then drilled new holes in the drum, had them tapped, and put in studs to then mount up the wheels to the truck. He also hogged out the center hole of the wheel so it would clear the diameter of the hub itself. The most troubling part is where the holes overlap and the stud isn't completely into full metal until it is toward the back of the drum. In my youth we rode around like this on the occasion that we took the truck out (about once a year during the summer) and he drove it like this for quite sometime. I'm guessing it is safe, there's a lot of metal in that drum, and it'll never go over 60 mph at the most. I do have plans to seek out a 5 lug hub (or if the price isn't too different, swap completely to front discs) and then switch back over to Chevy bolt pattern wheels. But would you drive it like this? It'll be done right eventually, just trying to get stuff done in order of priority; I'm adding a manual dual master cylinder and am going to run all new lines and install new wheel cylinders. Any input is welcome, and thanks in advance.
