Would anyone be able to measure the outside distance of the outer hinge pins for these arms? I tried a search without much luck. I was going to try and machine front and rear arms for a custom project. Any help would be greatly appreciated.

front - 1" (same as an rc10 arm)
rear - 1 1/8" (same as a 10t)

Thanks for the quick reply, I see after re-reading my original post I got just what I asked for. What I really meant is how much wider than stock the Klien arms are, the distance between the inner hinge pin and the outer hinge pin. Sorry for the confusion, I guess I need to learn when to stop typing and go to bed.

Just to resurrect this, I too would like to know what the hinge pin centers on the Klein A-arms are. Center to center on the rears would be most helpfull. Also, any comments about track width on the rear of the rc10 with the Klein arms and B4 hubs and cvd combo. -Legal?, too wide, could be wider, etc. I will be machining more purpose built reproductions and don't want to reinvent the wheel so to speak. Thanks -Jeff

the rear arms are like approximately 65 mm center of pin to center of pin. stock arm is about 58. most guys use the b44 rear cvd's with them because they're about 9 mm long than those for an rc10.
now, doug put an rc10 together with stock arms, b4 hubs and b44 cvds with no mods to the hub. that would lead me to believe that the hub difference would be approximately 8-9 mm positive offset compared to a stock hub.
that said, if the klein arm is 8 mm longer, and the b4 hub is 8 mm wider, that would make the track width a total of 32 mm wider over a stock rc10. that might be pushing roar max. then, there's the problem of finding a cvd that's long enough, and also making the front of the car wider as well..........

So for clarification, I can use the klein arms with stock, no modification, b4 hubs and b44 cvds without problem?

Raising this from the dead - was wondering what length hinge pins to use when mounting the front arms with the 10T bulkhead? Will the stock ones be long enough? I test fit the rears and they were fine but I think the stock fronts are too short. Maybe someone can confirm for me?
I saw a reference in the Old is New thread about B4 hinge pin sets. I looked those up and it doesn't look like they have the notch on the ends for the e-clip.

Sorry for hijacking this topic, but I'm trying to buy some arms off Dynotech but getting no response to my emails

Does anyone know if they are currently on vacation?
(I am emailing them cos I am in the UK so the shop doesn't work for shipping details)
