OK.... I know this has been done to death. I have searched Datsun1200 and Ozdat PLUS the net.
So much information to sift through and I am still confused.
All I can find is talk about using " stanza " stuff.

Now I have got 200B struts because I could not find 120Y or 180B struts if my bloody life depended on it. I have changed the lower spring perches to 1200 ones. Fitted 200B strut to 1200 ute.

Bits I have:

200B steering arms, lower control arms and castor rods.
1200 steering arms, lower control arms and castor rods.

Now to my bloody problem and HUGE confusion....

1. Which steering/control arm do I use?
If I use the 1200 ones I have to drill the steering arm bolts to about 12.5mm to fit the bolts of the 200B strut.

2. If I use the 200B steering/control arms I have to replace the inner control arm bush so the inner bore is smaller. Or drill out body for larger bolt.

3. The centre bore of the 200B control arm bush is larger than the hole in the body. So if I use 1200 bolt it will flop around in the bush.

4. Will always use 1200 castor rod.

So....... AAAAAARGH HELP!!!!!!!

What the hell do I do ? ?

stanza control arm, stanza steering arm, stanza ball joint.

With this, you can use any larger strut.

you need 120y castor rods also, not the ones that are same as 1200, the bigger ones

yep either those or the stanza ones.. it took me weeks to track down the stanza parts so good luck lol
