where can i mount my old alternator?

i got a set of Auto-Meter guages (water temp, oil temp, oil press., fuel
press.) and i want the guages to be directly over the driver's head in the
A/C duct (i never use A/C).  how can i route the tubing for the oil press.
and fuel press. guages back to the engine compartment?

does anybody know the number for ACDelco?
i have to get a water pump, a crank pulley, a water pump pulley, a
thermostat and housing, an oil filler tube (might use the one off the
Volkswagen engine).

where can i find headers that would fit into the limited space of the
Vanagon engine compartment?

this is what my exhaust system is going to look like after i find some
headers:

|| = exhaust pipe                                /      \
                                                |/      \|
/\ = muffler                                    |/      \|
\/                                              ||      ||
                                                ||      ||
 /             \                                /\      /\
|/             \|                               \/      \/
|/  =headers=  \|
||             ||

any help would be appreciated

thanks in advance,
