Sweet! Nice find!
My Kalifornia 1976 came with EGR, but I am told that federal didn't get them until 1978. The head dude at Colorado AIR who tested my 1978 FJ45 told me flat out that we don't need EGR up here on the old iron because combustion temps don't get high enough to make much NxOx. You do need the smog pump though. It doesn't need to work, just look like it's working. I had mine mounted but disconnected for about 15 years and she always passed every year. Just before the test I would throw the belt on, then take it back off after it passed.
