Hello all, I am new to the forums and to the Z but not new to wrenching. I have just inherited a 1972 240z from my aunt who was the first owner of it. This has been my dream car since i was a child and it is finally in my possesion!! It is about 99 percent original(had to change the drivers seat belt and couldnt find a factory one, and she had the seats recovered in the 80's) and I am planning on staying on that path. My question is was there a performance division of datsun that produced things like exhaust and suspension components when these were new? Something similar to what Yenko was to the Camaros. I would like to stay with factory parts. Also do you all think that this would take from the value of the car if I were to do this on some basic parts of the car. I have been searching around but havent found anything yet and figured I would go right to the source. Thanks everyone. Chris
