Commonality between '93 750ss & '93 900ss forks?


I was just wondering which parts of the '93 750 & 900 are common to both? On first inspection it looks like the gold anodized fork sliders may be common, but I wonder why the fork seals are different even though the fork stanchions are the same diameter? I ask because I have a 750ss in mint condition, but am fed up with the poor fork compliance on the road. I also have a (cosmetically) ropey set of 900ss forks that I could cannibalize for parts - but I would like to know whether I am backing a loser by attempting to swap bits over?
