Cheers for comments guy's
Well today used a bit of the spare ally and spent 1/2 hour doing a bit of ally bashing'n'bending.
Realised I must have a bit of Blacksmith in me.....
Ended up with a lid for the Cold Air Box...a bit rough at mo' and still has protective plastic on it.
But I figure a trim, grind, sand and polish and it should be just the job.
Might have to call on Wayne555 and use his expert polishing skill.
Has anyone got his contact detailed as I have only ever PM'd him on Sussex....and seem to of lost his mobile number.....
