I got a set of 88-89 crx si seats from a friend of mine for free they are in good condition, the drivers side foam is starting to wear out so I want to take my passenger seat out out of my 90 crx si and use that foam. best way the take apart the seats. also I am thinking that the seat pans are different. anyone know if this true, am I going to have to change out the seat pans? how much of a pain in the ass is that job. how do I take out the headrest in the seats?
