It is a combination of many things why I was looking at switching frames. $$ being a big part, I was told from another guy it was fairly simple with a 79 el camino frame. As for the skill I have very little when it comes to the mechanical, I am more the body type. It takes me longer to throw a sander then a wrench! Big reason to is this is going to be a daily driver and will be setting it up with air bags all around, thought it would be easier with a newer frame.
I am open to all comments that is why I posted. Thanks for all your help and suggestions.
