I got the one that comes with 4 leaf rear springs,new mounts,shackles,etc..Have had it for a couple of years,just now getting around to installing it.A friend of mine who builds street rods,told me this setup will ride better than the 4 pt.suspension with coilovers.Hope he is right.Starting it now gives me plenty of time to finish it before spring and the cruisin season,working at it in my spare time.I have a woodworking shop attached to my garage,and someone is always wanting something made in there.Always something to do.Who says retirement is easy?Course the thing is I enjoy the wood shop and also working in the garage on the trucks.
