OK chaps, your new mystery part number quiz is attached.
Graham at Uncle Melvyn's tells me that if he has any hope of getting me one, he needs a part number for the return pipe (that's the stainless steel tube) I have marked here running the length of the RED arrow and is partly hidden by the air trunking. I think there will be reference MCA plus 4 numbers teeped onto the mounting bracket that holds it against the heatshield below. Would any silver-top owners mind taking a look to let me know if they can spot this?
Also, if anyone can tell me the source for/ identify part numbers on the expansion tank AND bracket circled in YELLOW, I would be very grateful.
cheers, Colin
ps fingers crossed the picture is attached! It does not show up in message preview - so waiting to see what happens when I post.
