Demister vents

Hi All,

I need two Demister vents to suit my Austin 1800 Mk1 please, someone pulled to old ones out at some point in the past... are the Mk1 and Mk2 the same?? I guess yes??

Just the actual plastic bits that go from under the dash pad and then form a round tube to attach the pipe to... I should be able to get some pipe somewhere that will fit.

Thanks
