themechanic, can you measure the top part of the spindle? From the machined upper surface to where the nut for the ball joint tightens to. I know they are probably different due to different models, but maybe it can give me some reference. Thank you.I have the Doctor Diff spindles and brakes on front and rear with upper and lower Spicer/Raybestos Professional "Blue" Series ball joints. They came in a kit from Bill Rolik. These photos are from today with the suspension at full sag.

I have an OEM upper joint here and the stem is right at 2 3/4" long from the body edge and it has at least .600" of straight stem before the taper starts.Here is the ball joint. It begins to taper immediately under the ball. Cass at Dr Diff measured a known good one and it should have approximately 0.6" beneath the ball before it begins to taper. Definitely bad/incorrect ball jounts.View attachment 881949

I measured from the edge of the threaded body......so that one should be pretty close to the same...For comparison, re the described shouldered/tapered areas, here’s a photo of a removed OE upper ball joint from my ‘69 RR. Believe it’s the same as your ‘67. Hope it helps....Jim
