Size of opening for 914 gauges?

Anyone know the size of the dash opening in an older(1984)IM for one of the gauges? It's a 914 gauge, and I thought I'd ask before I have to take the gauge out to check the exact diameter. I'm seriously thinking of installing a multi-gauge from Westach. This gauge needs a 3 3/8" hole and has a 3 7/8" outside bezel diameter. The single gauge has four smaller gauges in it. I'd like to run an oil temperature, fuel level and two head temperature gauges (one for #1 cylinder and one for #3 cylinder). The only probably I can see is that the new gauge will not match the other two gauges.

Ron,

The gauge as you know will not match and I can almost promise the hole will be too big.

I replaced the 914 units in my 78 IM and had to reglass the holes for the smaller units.

The 914 gauges are 4 1/16 approx. (The Tach is larger) There are little instrument light pods and poorly fitting back plates that jut out a bit, but the gauge pod itself is 4 1/16 as are the stock 356 gauge pods. The reproductions in some of the kits may be different. The dash hole will be a bit bigger since it also has to house the rubber gasket/collar that prevents vibration and damage.

Those gauges that you're looking at are exceptional! Many of the VW catalogues sell billet surrounds that will "adapt" a gauge to several hole sizes and they look quite nice, several styles and size combinations. Check with The Real Source or BugPack for starters.

Good luck,

TC

Thanks for the info.
