This is the first late model limo style 3-way I have seen. Superior book shows 29 3-ways in 78 but does not break it out from there. Has been a Nevada coach its whole life. Just made a 300 mile trip with some minor glitches. Not sure if I am going to keep it as I have enough other projects. I have not had time to look it over to see what all it needs , they all need something at 30 plus years. If anyone is interested shoot me a PM .Thanks
