take it off and try different bolts ,even go to your local nut & bolt supplier then you will know what fit it is.

If you ring them with the jaguar colour code they will make you up the exact colour. very easy to do,I have done it many times on many cars always a good result.cheap as well. they give full instructions .

You have loads of parts that are in demand, mirrors dash , rad , put them on Ebay , you will get loads of money,whats the ski slop like & wood trim..switches , fues box , it is the little bits that add up.

Thanks for the welcolme ,
My Westminster Blue Jaguar XJS is first Reg 5/12/1996 4.0 Celebration so was one of the last .She has covered 87500 miles and is mint.
I have had many XJS my first was new in 1988 and was a 3.6 which was a company car and I am ashamed to say I was not at all kind to her I put 100k miles on her in 3 years but what a great car with main dealer service fantastic. my next was another 3.6 which I bought 18 months ago identical to my first except colour which I still have got .only done 67500 miles.I have had about ten 3.6 /4.0 since then which I buy as projects and bring new life into them I have a 93 ..4.0 facelift ready to sell.
But the convertable is the first one I have owned .I alway wanted one but did not want a V12 so when she came up for sale I was stung.Just waiting for the sun now.
