77 Dash Bezel vs 78 Dash Bezel?

[THE "10" SILVERADO]

You can put the later 78 bezel on there but it will obstruct part of the
gauges. If they are drilled out it wont look right.


I emailed them back and that was my response...I'm really getting confused because they used the same gauges from 73-80 but somehow the new bezel will make it to where I can't see the full gauge on the 77? Do they have different gauge mounts or something? I'm thinking that it will be just fine because of all of the people here vs the one technician at Classic Parts..
