Koni's The picture shows a Koni 82-1389 and KYB 5517.
They both fit in my 67 Fairlane using my home made springs. The KYB is a tube of gas. And feels like it.
The Koni is a heavy duty tube of oil and feels like it.
The Koni has 3 settings soft, med and hard. You have to take them out to adjust them.
Med is kind a like a 50/50 drag shock.
You can get front Koni's they are 82-1698. Special order.
Mustang front Koni's can be adapted.
Worth the price of admission.
