Hello Everyone

I have a few questions about gauges.
I am looking at replacing the gauges in the dash with some aftermarket ones.

Firstly, I would like to know how the gauge sizes work?
When the ad says the gauge is 5" what exactly does that mean?
1)The hole size that you need for the gauge?
2)The face of the gauge?
3)The total width of the gauge trim ring and all?

Secondly, I would like to know if anyone knows if someone makes Tachometers large enough to replace the stock speedometer in my 1949 ford club coupe. I think it is a 5 1/2" hole in the dash.

Thirdly I would like to know if anybody is using a GPS speedometer? I have been looking into them and was wondering how well they work?

Check with these guys. They can give you all the specs. Great people to deal with. Great product...Shark Gauges by Dolphin Gauges

These folks have several brands of gauges - eGauges.com - VDO, Auto Meter, Defi, Isspro and Classic Instruments Gauges . As far as a measurement, it's (usually) the case size that they use. Installation instructions for all that eGauges sells are on their website and include the dimensions. The chrome bezel around the face will add about an 1/8 inch.

What do you mean you would not touch one of those? Any reason why?

Check this website to see if it has any info on the Gps Speedometers. 4" GPS Speedometer Gauge 160mph (w/ turn signal and high beam). Auto GPS Speedometers From Speedhut.) Autometer has a Universal GPS Speedometer Interface Module that is Plug & play with any Auto Meter electric speedo. Auto Meter . BTW the mounting for 5" guages the hole is cut 4 5/8". For 3 3/8 guages the hole is 3 3/8". For 2 5/8 guages the hole is 2 5/8". Hope this helps.

Besides them being expensive, i dont like the thought of having to rely on a satellite to know how fast Im going. It will most likely have a delay too which will get annoying. What if you go through a tunnel? No speedo. Going through mountains, no speedo?

I guess those are all good and valid points. I will consider them all when I am ready to figure out what I am going to do.

I use a GPS to check my speedometer and actually drive with it in my daily driver on occasion. It is accurate but as said, some delay - possibly as much as 3 seconds plus in my area, sometimes, regardless of brand, takes quite a while to find enough satellites to work. My biggest concern with these gadgets is that they are expensive vs a mechanical or even electronic($125+/-) speedometer - $400 +/- with a sender

I remember when driving through mountains in north carolina the xm radio and gps would continually cut out. Really annoying. Can't imagine any of my gauges doing that.
