I'm looking for the '75 fog light bulbs. If you know where to find them, or have them, let me know!

It's an H-4. Most auto parts stores should carry them. Try Carquest.

The Cap'n

Wal-Mart even has them.

I found some at AutoZone. Haven't tested them yet, will tommorow.
I had to explained to the guy how/why I have to Porsches and I'm 14.

.....Sounds like he(store clerk) was "WHINING"!!!
(their readily available)H4's

I thought they were H-3 bulbs.
Fog light only needs a single filament bulb, H-4 is a dual filament bulb.

It is a H-3 for the '75s

.....Sorry.to misquote
(H-3....it is)"can you dig-it!"
