What size gauges fit a 1951 Chevy Coupe?

Looking to buy gauges for my 51 chevy coupe but I don't know what size to get 5" or 3 3/8" to fit right into where the originals are at.
Thanks

 

Interested as well. Can you post some dash pics as well?

 

nothing is a direct fit. I bought a set of NuVintage for my 51 as they also make an adapter to work with the factory bezel

 

@Boones You have any idea what size they are?

 

Look for a 5 inch quad set. Both my cars have Auto Meter gauges in the stock locations. There are many other makers with 5 inch gauges.

52 hardtop, how did you mount yours, the 5" was a little large if i remember unless I either cut the hole larger (and went without the bezel) or fab'd a mounting bracket to help center in the opening (or maybe they were slightly smaller, do not remember)

 

I sent him a pm..

 

Hey guys, I did use the stock bezels. It was the back side of the bezels that I had to trim. I didn't touch the new gauges. I have the new gauges with their bezels sitting in the stock bezels. Again with a little trimming I got them to sit nicely. I then took the old mounting brackets and cut them so they would sit around the new gauge body. I use the old brackets to hold the new gauges to the back side of the dash. It's been a while since I did them. I know there may have been more done to the stock brackets. i just don't remember exactly what it was. I may just look under the convertible as it was done last.
