On the 1200 I have, the right front control arm is bent. The tire rubs, My Question is will one from a b210/120Y fit. Or are they longer? If so I would need to swap out both of them.
Any help would be appreciated. Or does any one have a spare?

the 120y ones are longer and give a little more -camber.

I think there are 3 lengths? 1200/b210/Sunny(RWD types)
whatever they call em where you live, the newer ones were longer...

I got clobbered on this a long time ago, but here goes.
With respect to the front suspension, the B210(USA) and 120y's(everywhere else) are different. The B210 lower control arms mount on the out side of the cross member. 120Y, 1200, 210's mount inside the crossmember.
I'll scan an illustration from a Haynes manual explaining what I'm talking about.
Edit:



I f'd up the picture but you should still be able to see the difference

Even with North American models, there are two or three different control arms...depends on the year. The crossmember was also redesigned circa 1977-1978.
