Good evening,

 

trying to install this XTD clutch. 6 of 9 bolts line up.  Is this normal for after market pressure plates or is this a part that needs all 9 bolts.

 

I’ve tried researching the part number and haven’t found anything relating to it or if it is for Datsun Zs.
 

 

225mm Z clutches use 6 bolts, 240mm clutches use 9. What is the diameter of the friction surface on that flywheel? Is it stock?

Can’t say I’ve ever tried to put a 225mm pressure plate on a 240mm flywheel to see what bolts line up.   Should go do that

It’s not stock.

6 of the 9 line up. 

Appears something’s not right here. 

what was the clutch sold as for? 

I have a XTD RB25 clutch and flywheel in my Z and the bolts and dowels only line up in one position. (i. e. no rotational symmetry). 

 

280ZX. I hate having parts order 10-15 years ago and finally doing the build. I believe my flywheel is 225mm and clutch is 240mm.

are there any issues with mating them togethe?

you'll need a new clutch release collar to match the clutch (assuming your old clutch is 225mm) 

might be better off getting a 240mm flywheel too.

Just measured both the pressure plate and friction plate off the flywheel. Both are in the ballpark of 226mm-228mm
