I just got new plugs for both my 75 and my 78, they both take the same plug. W6DC non-resistor plugs. It would be unusual for them to change for 77, then change back for 78. Are you sure that's the right number?

How many do you want? I can get you 1600 of them, about 2.50 each plus shipping from az.

I have 16 W7DCs that I no longer need. PM or email me.

Interesting. The Bosch site shows the same plugs for '76 and '78 but no listing at all for '77. It's gotta be a glitch.
