Or use Oeticker stepless ear clamps. I used reduced size hose for the suction since #10 ferrules fit perfectly over it. I have boxes of hose and ferrules, though used much on my classic cars too.

Wouldn't be practical to do for you, given shipping costs and the need to mark the clocking of the fittings in the car. If you won't do above, take the hoses in to a shop, though they may balk at cutting the thick collars off, and doubt they could source the funky fittings M-B used.
