This is for a brand new set of adjustable spring shackles. They are universal design that fits a large number of cars. They are made by Rocket Racing Products. Part number R1300. I had bought for a 1967 Mustang but sold the car before getting a chance to put them on. Very handy for adjusting the rear ride height of the car to eliminate sag and to give it a slight rake. Only asking $35. If interested, please email me at this ad. Or you can call me. No texts as this is a land line.
