ZSPEC's Datsun Z Clutch Master Cylinder Cap Cover - 51mm I.D. (Inside Diameter) x 16mm (Inside Height). Fits OEM CMC and most aftermarket - please VERIFY size of your cap before ordering.
Our reservoir caps are true billet-aluminum and ZSPEC original designs. Each has eight edge "ridges" to help provide a grip surface for easy tightening and loosening.
Available in several finish colors with or without logo. Allen-key is included and the cap attaches by simply slipping over the OEM cap and tightening the two set screws to the existing reservoir cap.
** Please note - it is your responsibility to measure your cap to verify fitment BEFORE purchasing. Returns only accepted in NEW, unused condition.
Includes Allen-Key for Installation.
