smkn951

went to the local strip yard looking for visor clips. no luck, instead i saw 2 924 blk and orange. both cars still have the vdo boost gauges on it and temp and etc. are any of the parts on the 924s interchangeable with the 951?
the ppl running the place offered to sell the red porsche plate that goes between the taillights for ten bucks and the vdo gauges for 5.
can i use them on my car?
what else can i get? seems like they don't know how much this stuff is worth, so i'll get as much as i can.
