Hi All, Darron from England New member,

I have a 63 fleetside longbed, big window, i want to lower the rear end bu first i need the following information, Measurements of the folowing please,
From top of differential housing to bottom of bed wood, (i have 6")
From top of axle to bottom of chassis (i have 5")
Overall stock wheel outer circumfrance, (i have radir 15")

I think my truck has been lowered a little bit but im not quite sure, I dont wand to spend money purchasing lowering springs only ti find i have them all ready,

I want to lower the truck at least 3" from its height at present & would like to have 2" for suspension movement,

Has anyone purchased a kit fron CPP or any other company ??
