These two clamps fit Series 3 and possibly Defender Land Rovers.
They are not ‘handed’ like the Series 2/2a clamps.
The Genuine Series 3 Part Number is MRC 2416 which appears to be no longer available. What is now offered is RTC 6159.
This is a Defender part number, which fits the Series 3.
The after market price of the replacement clamps is over £25.00 each plus VAT.
This is a Genuine Series 3 used part in good useable condition, but could benefit from some light restoration as they have some surface rust.
The threads on the posts have been cleaned up by running a die down then so that the adjusting nuts move when required.
These are not library pictures, the buyer will get the ones shown in the photos.
