I thought it might be as it didn't fit right, about an inch short on either side.
But now I have holes in my bootlid that I need to repair as the previous owner fastened it on with wood screws!
I also put the Mrs to work painting a few bits for me.
The old bottom water pipe was doomed, so I made a new one from 15mm copper pipe.
Also removed the old linkage that had seen better days.
Just waiting for some 6mm rubber mat to show up, so I can make a gasket to put between the shifter and chassis as they apparently vibrate like hell without it.
Thanks for the comments.
