Frt LCA length ?

[smugley]

Can anyone tell me what the length of the Frt lower control arm should be ?

I am currently rebushing my 71 240 race car and found that it has two different length control arms on the frt .

LHS is 296.5 RHS is 286.5 ( measured center of ball joint hole to center of inner bush hole )

They are not modified and look factory made to me .

Could one be of a 510 (1600) ?

Thanks in advance for any help .

Cheers Doug

Front end of car is bent.

What was its alignment settings?

A suspension shop may have compensated to btain close wheel alignment by cutting and joining, it can be done without being obvious.

Both arms on close inspection have not been modified .

No idea on alignment settings as inner bushings were basically falling apart .

Car has been sitting for years ( last log book run was Rob Roy 2005 , past owner )

I would just like to know what the correct length should be ?

I think i just opened a can of worms !

Cheers Doug

Might have an arm from another similar Datsun model? I have a front end off a 260Z I can measure to compare both arms...

On my March '72 car they are close to the 286.5mm measurement.

My car has had a hard life ( Before me ) so maybe it has at some stage picked up an arm off off a latter or earlier model ?

It would be nice to know if all S30's came with the same length arms or if they got longer or shorter in between models ?

Ie 240 and 260 frt hubs are different offsets and so are the arms diffrent length's ?

Thanks for your replies Doug
