1960 Upper ball joint question

[72bigred]

Hi,

1960 1/2 stock A arms.

Finally got everything cleaned up/painted and ready to install these drop spindles.. I got some nos lower ball joints and have everything but figured I would pick up the uppers last. I am at that point and I have a question.. In some parts books I have it appears the uppers are the same for any chevy half ton from 1960 to 1970.. This brings up a question in that if I purchase uppers for a 60 they are 60$ each while the uppers for the 70 are 35$ each.. Is this just a pricing thing due to year or is there an actual difference I am not aware of?

Thanks,

Skez
