I've got 5mm shims and have tried everything.... but neither of these will work too well. I can explain relatively quick as it can get complicated. This is for the rear of the '89 masami yokomo with the wide rear white arms and modified RC10 rear hubs (as well as moded camber link position on that hub). It seems that this setup offers a lot of camber change throughout the suspension travel causing the universal to bottom out in the diff-outdrive rather quickly if the universal length is just a tiny bit too long. So, basically to utilize the full shock travel the universal has to be right at the edge of popping out of the drivecup at full suspension to ensure that it doesn't bottom out at full compression. To add more crap to this I could just use the ZC422 and put 1mm of shims before the first bearing (same as your o-ring idea) but then the axle portion of the universal doesn't sit flush with the aluminum wheel mounting hub (the axle is recessed by about 1mm) and since I'm being overly anal I'd prefer not to do that. This is why I need such a specific dimension and was hoping the ZC422A could work.J.M. wrote:Hi Jeff,
I have seen people use an 'O' ring on the shaft which is slid into place before the first bearing goes on.
Im currently after the 422 if you are looking to part with a pair or two.
It is just the plain ZC422 - no extra letters at all. Different offsets should still be fine - even if the axle portion is a little longer that would actually help one of my issues. But then again, it could also be shorterCharlie don't surf wrote:Jeff, which 422 is that- I don't think that the rear 422a and the wide front 422 for the 870c are the same part exactly ie different offset at the hub
I actually do have a nip set that I thought I needed but seem to have freed themselves up!!J.M. wrote:Im currently after the 422 if you are looking to part with a pair or two.
you might just not have enough internal spacers in your shocks? I will measure both sets I have for the 870 wide front ( and axle portion ) and the rear 93 set ( and axle portion ) tomorrow to see what if any difference there isxxxmain wrote:I've got 5mm shims and have tried everything.... but neither of these will work too well.

Thanks Peter!! That does suck though... I was really hoping they were a bit longer.pedro wrote:Hi Jeff
I just measured some nib ZC-422a that i have here and they are the same as ZC-422 they just have a longer flat on the end?
