Dang a challange!!!! Prove him wrong please. I loved muscle cars when I was young. But 1k for and upgrade on brakes?!?!?! That's way too much! Plus its not original anymore. I had Dusters, Mustangs, VW and they are way to expensive when it comes to parts. Datsun is funner and cheaper. Go to the junkyard get some some 280zx struts and calipers for a brake upgrade on a 510 and it will be way cheaper than 1k. Ohhh your head messed up? Thats ok cus can swap the engine out of your datsun car and swap in another one. Matching numbers? Who cares, when its fun to drive and it dont cost much to fix...
