hey, ive been lurking over old posts and tech articles for a while now and i decided better get in, ive been working on my 30 model A tudor for some time now (just finding the right parts) right now im looking for some guages for my 1931 Cad dash, the hole sizes are going to be a problem and i'd like to not open them out a little more if i can.
there 3 1/2" and 1 7/8" . the dash is pretty cool with the turned stain. inserts on ether side of the center cluster, so im trying to keep it that way as much as i can.
Any ideas?

 

You're still on the intro thread, won't get many answers here. Anyway, welcome from the Netherlands!
