topline rear brakes same as stock 914?

[721302]

i have heard that toplines rear disc kit is just stock porsche 914 parts but cant find a definate answer anywhere. The reason i ask is because i found a guy that has one (maybe 2) 914's he is going to part out and i can get the rear disc for about 75 to 100 dollars. I know the 914 is 4 lug so i figure they would be good with the topline front disc i just ordered so i can have front and rear disc. any other parts i should try to get off of a 914 to use on my car?
