Lukas,
Thank you. I got in touch with the original owner who sold the car to the guy I purchased it from and he was able to answer some of my questions. Bottom line, the car is a blast to drive. My wife is a bit skeptical due to the cosmetic condition, but I'm pretty sure the other lady in my wife is convinced it was a great decision!
That being said, I've finished a couple small projects - The weather is still not ideal, but I need assistance with installing the original tachometer which I have in a parts box. I'm not electronically inclined, but have a decent mechanical skill-base. I know there is a tachadapt kit that a user on the site sells for around $70, but anyone have any idea as to how to go about wiring it all up? The car currently has working gauges for water temperature and oil pressure only. I've contacted Renegade Customs as of this morning, but their harness states it only works for 1974 and later cars.
Any help would be greatly appreciated!
