Stihl bar mount patterns

[boda65]

What is the difference between the 066 bar mount and the 088 bar mount? I am trying to fit a 36 inch bar to a McCulloch SP105. I have it on good authority that the 066 mount bar will fit with just oil hole mods. But I found a good deal on a 088 bar. Is there somewhere that I can find specs with measurements? Thanks!

Good info, but which bar is which?
