Are these just to take up the slack between the 14mm bolt shanks and OEM bushings?That’s for the subframe, need the rear diff bolt bushings, 16mm OD, 14mm ID

If so, how long should be the sleeves?
because the freedom of movement is both up and down? And the morons at Ford put a 14mm bolt in a 16mm hole?I'm wondering if anyone has tried an old-school solution, why not just use a pinion snubber?
The primary force being applied is up, which is what snubbers are for. The only force pushing the pinion down is from decel which engine braking can only apply a small amount of force. Braking forces are translated from the hub into the chassis directly.because the freedom of movement is both up and down? And the morons at Ford put a 14mm bolt in a 16mm hole?
A kit as you described is available.Maybe this has been discussed, but why not through-bolt the rear with a larger diameter (16mm) bolt? All you have to do is drill out the threads in the ears on the diff.
I’ve see one for the front diff mounts where you drill out the threads in the bushing, but so far haven’t seen anybody drill out the ears on the diff cover and through bolt the rear. Would make sense if it had been done though. I might yank the cover off mine next time it’s in the air and have at it, just need to pick up a good HSS 16mm bit, cover is aluminum it should drill out easily. I’ll check the forward face of the ears for flatness and square with the hole, may need to be cleaned up a bit to mate well with a washer and nut.A kit as you described is available.
