carpet interchangeability question
 

OK, I know that coupe carpet does not fit quite right in Cabs (and targas I think as well). The reason is the front pieces right (narrower on cabs and targas?)?

So then, is Cab and targa carpeting interchangeable. The part I am not sure on are the rear pieces behind and on sides of rear seats.

Just want to figure this out before the next good deal comes along...:(

Thanks
