I have a Land Rover roof rack for my 90 but parts of it could do with being freshened up, I've got the original manual and I've searched through microcat for part no.s but can't find any. Does anyone know where the following bits could be replaced from?

- the rubber seals that sit on the feet of the roof rack and on the brackets that screw to the feet on the gutter rails.

- the metal plates with the two nuts welded to them that sit inside the feet that the lower brackets then screw into.

If try and add some photos with the bits highlighted.

Any help appreciated!
