1990 300 Se Driver Window
 

Need to replace drivers door window regulator 1990 300 se. Don't know for sure but was told there are 2 different styles. I believe the one is brose don't know the other. Can any one tell me the difference. The one in the car now resembles holey iron strapping and not solid parts. I am assuming they are not interchangable in any way. Also is there a DIY link for this procedure. Thank you
