Otherwise, there is a lot of work involved in transplanting the FM section from a newer radio into your existing setup. There is no easy way to make the conversion as there are more than just a few component changes.
As an alternative, youcan check out Hemmings to see if there is an ad for a company to make the conversion of your radio into an AM/FM (plus tape if you desire). There should be more than one company, but they will not be real cheap.
