I've made some progress on my ole 78' 280z.
I've gotten the original AM/FM radio installed. Thanks to Slave2anMG for sending me his radio! I got an aerial switch off eBay. Everything now works! Aerial goes up and down! I also got the clock working and the map light fixed. Had to put in a new shift boot and a new shift fork boot.
My interior is now back to factory original shape.
I also stripped out the aftermarket cruise control that didn't work.
