Lower Ball Joint bolts needed for K-H setup
That should be 9/16 x 18 Fine thread Pitch.
And 1 3/4 inch bolt length.
You did a miss type on measurements, in your reply, that i need to correct you on, and fine thread pitch.
Now as far as caliper to spindle bolts go, the OP hasn't said anything about needing them, wanting them, so i assume he has all 4 of them.
At one time, for a long time, i thought those factory caliper mount bolts absolutely had to be used.
But in the real world, you don't have to use them.
Regular 7/16, Grade 8, works just fine.
This had been discussed, written about, hashed out, numerous times in the past.
In the past, i have rebuilt, put back into service 32 of these 65-72 Kelsey Hayes, 4 piston, disc brake systems.
Sometimes they were missing one, two, three, or maybe, all 4 of the factory type bolts, so i just used McMaster Carr store bought bolts.
In all the decades that i was doing this rebuilding NOBODY, has ever got back to me telling me there was any kind of problem with caliper mounting using regular bolts.
At one time a guy up in Canada was reproducing them for awhile, put after he ran a batch of them off, it quickly came to an end, after they sold off.
Well, here i go again, and ran off my 2 cents worth on the subject at hand.
