New cam bolt question.

[Crazy4408pac]

While checking on new upper control arm cam bolts, I noticed there were two differant ones. One that said, + - 2 1/2 degrees and another that was + - 1 1/8 degree.
Which is the correct one? Why the differance?
Going on a 72 Swinger.
Thanks

Never heard of such a thing, but get the ones with the most adjustment.
