Hey guys,, I'm new to this forum.... I have an 82 El Camino with 305/350

I have a dashpad from a monte carlo 84 or 85,,, very large hole in dash...

I read somewhere about intalling the Delco AM/FM/CD from a late model GM,,,

My questions are what yr will work? and how much modification needs to be done?

Very anxious to do this.

Thanks
Ray (82 meeno)
