What GM OEM radio/cd will fit an 87GN?

[Steves87]

I have been reading some of you installed a GM OEM cd deck out of another type car and it fit and looked like stock. What years will work in an 87 GN and where could I find an adapter for a simple plug and play?

Mine came from 99 Tahoe some modifying to brackets necessary.
Any GM radio with fan in back like your computer will work.
Adapter kit is available at Walmart, Bestbuy i perfer bestbuy
more expensive antena plug longer.
You will enjoy the difference in sound i did with stock speakers.
