Gauge questions

[sixty4bigwindow]

Hey guys,

Thanks to you guys, I got the correct temp sending unit from lectriclimited, and that is one more functioning factory gauge! The last one to get functional is my oil pressure. Since the 64 one is the mechanical gauge (I think?) I can't wire it up to the electrical fitting on the back of my intake manifold. (Truck was stock 6 cyl, the motor is a 327.) Any ideas on getting the stock gauge to work with the newer motor? I'm kinda lost on how to convert anything over to that.

And as usual, the tight budget (free>real cheap>probably not going to happen,) is my process of elimination lol.

Thanks fellas!
