I bought new springs for my 68 last summer and General Spring were the best deal when shipping was considered in the price.

 

Leaf Springs 1942 - 1972 Ford F100

 

NumberDummy I have a 62 F100 unibody I have been doing a frame off resto I had my springs all disassembled lined up just like they come apart. My misfortune I had just painted them with POR15 and letting this heat wave bake them. I had to leave some parts had come in and went to get them, it started raining bless their hearts my wife and daughter in law run out grabbed them up and jumbled them all up. I have the parts manual on CD and as best I can figure out I have a C5TZ-5560-F the numbers match as far as the diagram with the A,B.C.D but by diagram which is the front and rear? My tag in glove box says F10JH195448 thanks for any help finally got them all separated and was amazed it even mattered how they stacked judging the distance how they centered up
