Anyone Have a 64-66 W/Factory Original V8 and Gauges?

[MikeN]

My 64 C10 was originally a 230ci 6cyl with idiot light dash cluster. I have swapped to a 350V8, and purchased a flawless instrument cluster with gauges at a swap meet awhile back. Two questions...

1) Where does the sending unit go for the factory coolant temp gauge? Intake manifold? Passenger side cylinder head?

2) Anybody know where you can get the brass fitting(s) to run the copper capillary tube into the back of the oil pressure gauge? Anybody know what this fitting looks like, or have a photo?

Thanks in advance!
