I have to get a 7 degree reamer to ream the drag link hole in the steering arm of my '34 project, which got me thinking about my (stalled because of the roadster) '63 Riviera project. I have new original style ball joints in the control arms, and I'd thought of using a pair of '93 Chevy Caprice spindles and disk brakes, complete, that I have on the shelf. When I tried to test fit, if memory serves the Chevy spindles have a larger hole for the upper ball joint. Does anybody know if these are 7 degree like the Ford reamer I ordered? I could weld the holes full, re-drill and re-taper to fit the Buick ball joints, and "Bob's yer uncle", disk brakes for the Rivi for FREE!!
