mustache bar confusion

[highway star]

I removed the mustache bar over the weekend in order to replace the rubber bushings with some urethane ones. the bar was in a shocking condition with the retained outer metal part of the bushing severely corroded and i'm gonna have to scrap it the bar. however i think i have the wrong bar fitted. I have a 74 260Z and according to MSA website i should have a curved bar, but (although it's a little twisted) it looks like the straight bar from a 70/71 240Z. So, does that mean i have the wrong diff ? Any advice appreciated.

I have to say it looks fine to me.

It looks different to mine - mine's a mid 74 260z, and here's what it looks like.
I think mine would never sit like yours on a desk like that because of the curve in the vertical plane.

It can not be wrong if it was fitted before.what diff is fitted

dont know which diff it is but I think i've been getting confused by looking on a US website which may have different type's than Euro one's. according to MSA it should have had a substantial curve possibly for a longer diff. which made me think the diff may be wrong. spoke to Pmac and may have it sorted now. On a different note, is their a factory service manual available for Euro markets? US versions pop up on Ebay and there's an Australian version available on CD rom, but how much is applicable?

 

[jonbills]

I don't think the service manuals are territory specific - certainly the ones I have cover us/aus/eur markets etc

Better to look at the rear cover of the diff rather than trying to work it out from the mustache bar!

afaik, the r180 bar can't be fitted to an r200 due to the holes for the studs in the diff rear cover being different sizes.

74 260z should be R200 right? unless it's an auto perhaps?
mine is deffo R200.

This picture might help too. Note the way the bar comes off the rubber mounting at each end i.e. it's different for the R180 compared to the R200. From memory I think the Haynes and Autobooks can be confusing here because they show the 260Z with an R180 only. I managed to fit my bar wrongly when I first upgraded to a R200 because I looked at one of these manuals for the orientation of the bar - no wonder it was a bitch to fit (and then I had to take it off swap it around!).

that's a good picture .
