Patch panel ?'s

[WunTon]

I've searched and haven't seen a definitive answer to my question. I'm looking to source some patch panels for my cab floor (it's a 63) and I've come across panels listed for 60-62, 63-66 and also 60-66. At first I thought it was just different manufactures labeling them different but then the more I dug the more I found that most manufactures have all three options. The 60-62 and 63-66 options seem to be priced about twice the cost of the 60-66 option but I can't find anything that really lists a difference. I'm aware there are some differences between the model years but I'm not up to par on everything as many here are so I figured I'd ask and see what experiences others have had.
