Rear springs. Have a look.

Yep. Looks just like the ones I just took off my 68.

If your gonna buy new ones here's a tip. I bought mine from Mancini's cause they were cheaper by a few bucks. They didn't list their shipping cost. Now I know why. They gouged me for $40 to ship a set of springs and didn't even tell me in the e-mail what the shipping would be until I recieved the springs. If I would have bought them from Summit I would have paid $10 more for the set of springs but only $8 for shipping. So in essance they would have been $23 cheaper. Something to thing about.
