67-9 Dart/Barracuda Console mounted tach base

Do you mean I'm correct in my analysis and conclusions??? Wow that doesn't happen often. Lol. Yeah still trying to figure it out. Don't want to file the locator nub thingy but might have to.
Thanks
Yes, that sounds correct to me. The tabs don't really appear to me to be locaters, but to finish off the groove. It would look funny if there was a gap in there.
