I used the turbo/2+2 ZX 240mm Clutch and a lightened flywheel. This is a stroker motor correct?

Correct. 3.0 stroker.

now here’s a dilemma. The flywheel below was pulled from a 2+2 in 1995 or so. It was a ‘77 2+2 at Autogator in Sacramento. But I only unwrapped it today. What do I have? Did someone put a coupe driveline in a 2+2, or is this a 2+2 flywheel? 

Some of today’s progress: got the fan clutch from Z car depot while talking to a Datsun 510 buddy in my driveway. 

My Datsun buddy had come by to drop off the Jeep CAS he had modified for me at the body shop. (We did three of these so two are for sale) 

Need more pics of yours. I have a couple of them at the shop.

Hold one for me…. Will talk later..

Looking at my 225 and 240mm hubs, yours looks like a 240mm. I took some measurements of the friction disc of both and a crappy pic of the difference in the hubs. Hope it helps.

225mm

240mm

Cliff's method works.  Another is the bolt pattern.  Nissan did not drill theirs for both.  225 is 6 evenly spaced bolt holes, 240 is 3 sets of 3.

Thanks Zed.

I won't have to climb thru my storage building again.

 

I just found this from zkars too while you were posting.

Well after more than an hour on the phone with @Yarb today, I’m closer to a flywheel decision than I had been. Hopefully I didn’t get him in trouble with his wife as he only had 35 minutes to get to Publix and do some grocery shopping before they close. Thanks John! 

Does anyone make a billet distributor hold down? 

Copied this from @rcv post on throw out bearing sizes.

I just ordered the 13# flywheel @Yarb is using. Can anyone confirm that there is or was a problem with the ARP flywheel bolts? Did they correct it?
