Most recent photo shows the Instamount part but hopefully the P.O. did not remove the lower metal bracket with 2 holes that located the housing assembly. Good luck

 

😍😍 yes this looks promising... I will update it once I receive it. Thank you everyone for help. Very appreciated! I will try to give back to this awesome forum as soon as I have anything valuable to share.

Until then you can watch my garage videos related to Jaguar. Luckily all my cats have been good cats, so not many serious issues, but few repairs on there too already now. More coming of course with my XJRS Project...

The box is very easy to find and cheap. Mine broke some weeks ago (brithle plastic) and i sourched one form Ebay for 75,-- quid. Autoreserve have them too but importcharges and VAT kills the trading with UK. Mine came from Lithouwenia.

 

Yes, found it already, hope to get it soon, just now collecting few more ideas to use the parcel...
