Re-Drilling Hubs

I just sold a set of 9" brake hubs, conveeted to 4.5" bolt pattern. Unfortunately I deleted the picture I took for the ad, so I can't post it. There's plenty of metal on the front hubs to convert. I had them CNC machined to the 4.5" bolt pattern in between the existing holes, with a larger flat machined on the backside for the heads of the studs. I pressed in Raybestos 6184B 1/2" studs, which the shop had for measuring before machining. The 10" hubs are similar and can be machined just the same.
