Here's a bundle of caps for a brake master cylinder and a clutch master cylinder removed from a 1983 Datsun 280 ZX. There is common wear signs of vintage car parts. There appears to be no breakage. The finishing on the metal caps has lite surface rust , which I will clean . These items should have fitment capability with most 280ZX model years. Please view our pics for your assessment of condition. And good luck with your Datsun Z car restoration. Thank you for viewing this posting
