Hey Fellas.....I have searched the site for gauge sizes for a 78 camaro with no luck. I would like like to replace everything and was wondering if someone knows the correct sizes........Also is it possible to install a shift light in the dash? And one more thing....can I use Aprils "How-to-Guide" for my application? Thanks guys.

I believe the sizes you are looking for are 2 1/16 and 3 3/8. Of course, if you are using your stock carrier, than modifications will be necessary (like April's). I think you might find a shift light thats part of an in-dash tach, check out Jegs or Summit.
