Have a metal dash hole size 4" for older speedo.........replacing with smaller speedo for hole size 3-3/8".....are their bezels out there to enlarge instrument size to cover larger hole?

You need the FL37538. You can get it from CP or Hardin.

Thanks LS1.........You made my search so much easier!

I posted a link in you speedo thread with the adapter bezel info

Griff I completely blanked on that....thanks so much for the link!
