leaf springs

i have bought a 33 ford pickup i have patterns made off the leaf spring kit from chassis enginering for the mounting plates that hold the leaf springs in place for a 34 ford frame does any body know what the leaf springs in the kit are close to as far as length or width that could be found in a salvage yard

 

somebody got any suggestions???????????? id like to save about 452.00 to go toward other parts

 

Pretty sure they don't use springs from a donor vehicle, you might want to call Chassis Engineering and order a set.
