You double drilled a Chevy centerline for 5 on 4? Interesting!
I've got two pair of 5 on 4 centerlines that have been double drilled for 5 on 4 1/2. They used a smaller center hole to leave more meat around the small pattern. Back side of center holes were opened up partially thru, so the wheels can still use the small CL caps. Wish I had some, lol. Also have a pair of 15x12 CL autodrags that have been double drilled 5 on 4 1/2, 5 on 5.
As to the center register, there have been billions upon billions of miles driven on non-hubcentric wheels.
