ok i have a 79 monte carlo landau, the old dash is ruined, so i want to do some mods to it, can i change to a 84 ss monte dash, or is the bolt pattern not going to line up very well, if not the 84 ss monte dash, what could i use in replacement of it. thanks

 

Got a pic of the 79 dash?

also check bolt locations my 84 and 85 both are 4 across the top in the defrost duct area, two that come down from the middle behind the radio and one on each at the botom right by the door
