I just put new springs on my 67 this past week. I put the mounting brackets from n.p.d on as well. They fit great. make sure you get new bolts and clips , if your brackets are rusted out then i am sure you will need the new bolts and clips. I also made sure i coated the car heavily with POR ( rust prevention!)where the bracket mounts.POR is also sold in the n.p.d catolog. Great stuff!!
