Just wanted to ask if a power rear seat from an '84 500SEL would fit on my '84 300SD. My guess is that the seat back would fit fine, just that obviously I won't be able to use the power adjustment feature. Am I right in this thinking or not?

Additionally, I wanted to know if there was any means at all by which I can integrate that power seat into my 300SD and make it work. Obviously I'd have to get the switch and such, but does anyone think this is even possible? Thanks.
