I don't know if your car has the bomb or not, but that's fairly easy to 
check. The bomb is usually visible in the left front fender when the door 
is open (at least it was on the two 5k's I owned) the ones I've seen were 
bright blue.

The vacuum assist is a can about 12"-14" in diameter, maybe 3-4" thick. 
It's connected directly to the rod from the brake pedal as it comes out of 
the firewall. It's easy to test it: With the engine off, pump the brake 
pedal until it becomes hard (should take a few pumps (maybe 5)). Hold the 
brake pedal down while starting the engine. The pedal should sink as the 
vacuum builds up.
