I have two of the Datsun Competition catalog single row harmonic balancers. I will be using the Performance Products one on my new Rebello motor so these can go to good homes. I have no idea what these are worth but I'm told they're rare and NLA. They don't seem to be in too bad shape though they are used. I'll post pictures later. 

Ill price them at $125 + shipping and if they don't sell, I'll reconsider that...

This one is on the engine that I am replacing. I bought it years ago. The other is in my storage garage. I also bought it new and had it on my 280Z until some drunk hit me from behind one Friday afternoon...

Sorry didn't realize you have it on a 280. I think the belt width is narrower than my 240.

It's not. That's my 240Z. The other one was on my 280Z. I have two. And before we muddy the water, Datsun Competition Catalog only sold one under one part number for the L6 motor.

the car it's on...

Will you take 100.

I think one of them is sold at $125 so, not until number two doesn't sell for a week or so.

I think $125 is a really fair price...

One sold. 

I forget Patcon. I bought both new and I have an old Datsun Competition Catalog here but the price list was a separate sheet and it's not around anymore...

AU market 240z's had these as standard.

We never had an air pump FYI on 240z's sold here.

Yes, they were sometimes called the Euro dampener as they were also used in European Z cars. They were sold in the Datsun Competition Catalog as Euro Dampners. That is where these two came from.

by the way, you two who bought these, I will be shipping them out Tuesday when I get home. Thanks again!

For sure. A NLA factory part like that is worth it. If I did not already have one of those, I would have been interested as well.
