I have all the parts you need 76 fuel/voltage gauge like new condition and r-200/3:90 diff if i read your a/d correctly.Send me a p/m for the rest of details.
I have a good straight 260 Z door passenger side no rust just straight in blemished white. No door panel or window glass or lock mechanism $150 picked up in Modesto.
I paid $1180 shipped two years ago and have no use for it at this time. I'll trade for three good cylinder heads rebuilt P90,P90A and N42. If this is workable let me know what you have. Thanks HB-Z.
