Wanting a 87 radio with harness in working condition

Here is a nice set of lap belts that I don't need to hold onto. The seatbelt tapes inside are nice and would be great to replace the automatic belts that are frayed/faded.   http://i1187.photobucket.com/albums/z388/starionkiller/parts%20for%20sale/th_SAM_2459.jpg

I know the doors are 5 1/4. Are the rears the same? And the dash the same also?   Thanks   Tony
