Thanks for that seamus, you can tell you fitted yours much more recently than i have!
I have a habit of keeping one of those mini-tins of WD40 in each of my toolboxes (main big toolbox in the house, and a smaller toolbox in each car). That's why i suggested it for use of thread cleaning, i sometimes forget that not EVERYBODY has WD in their toolkit.
With regards to mike's point about the philips head on the bolt on the top mounts, mine was seized into position too, (don't re-use it for god's sake!

) I simply could not get a purchase wit hmy trusty,chunky ratchet screwdriver, i had to use a big philips headed socket on a ratchet to get enough leverage to free it off,and even with the ratchet, i had to use nearly all my bodyweight on keeping the ratchet in the crosshead of the bolt without it rounding it off! I'm sure the philips head bolts wer brill in 1995,but not now!
