My 62 SV1 Valiant sedan

I widened some old wheels for the rear of the car.....small stud pattern.....made them from 4.5 x 14 to 7 x 14.
I had to specially sharpen a drill bit, 5/8", to drill out the spot welds in the skinny rim.
I also had to use a Rotary Hammer drill, ya need some grunt to turn that drill bit.
I had to cut out the centres from the donor rims.
