DATSUN - KONI Sport Adjustable Gas Strut, Rear, 74 260Z 2+2, 9/74-78 260Z-280Z.
I bought these new from Motorsport Auto - The Z Store.
Ordered October 2023. I ordered the wrong ones. I didn't realize I needed shorter ones for sectioned strut tubes. I had to reorder the ones for rear 240Z, those fit well. Mechanic tried to install one but it was too long. That one is cosmetically scratched up. The other is brand new. I paid $373 shipped. I'll sell the two for $250. Prefer local pickup. May ship if you want to pay actual shipping.
Thanks for looking,
