water temp gauge WTF threadsare these! I have a hole in the drivers side head with a temp sender in it for the computer. I need to put an autometer water temp gauge in and I can't find any place with a 1/2 inch or 3/8 pipe thread for the gauge. The drivers side head looks like it's tapped 3/8 but the passenger head has this weird plug with a weird thread. Any ideas? I have an electric water pump, could I pick u the water temp from one of the holes where the heater fittings are supposed to go? I have no heater. I guess I could drill and tap the passenger headn but I'd rather not.
Thanks

If you do a search on this, you will find exactly what size adapter you need. I don't recall the size, but I know you can get it from Autobarn.
The connection I used was on the pass. side head. You will probably need to remove the starter to get up in there and loosen the bolt (it's an allen head). It's a bitch to do if you don't have a lift.

I believe so. I think that there is one straight up from the starter, and one off to the side. Make sure you have a drip can when you pull the plug. You will drain quite a bit of coolant. I'd wear some goggles. 
For this location, above the starter in the block, you will need an M16x1.5 adapter, avaliable at Summit, Jegs, or E-gauges. And yes get a LARGE can to catch the coolant and get out of the way when it comes out. I got a mouthful of that stuff and it wasn't pleasant
