I dont know what to do with my wife...

A mental health professional or divorce lawyer?

Actually, it could be a whole lot worse. She could want a new Mercedes or something else that is $$$$$.
I think old El Caminos are kinda neat. Find a nice one,throw a decent small block with air and a 700R4 overdrive tranny in it and she should be happy.
Apparently she was cool with your little project so give her something back. AND you can use it to haul MOPAR parts for your next project in it.
