Interestingly enough, the last time I went thru this(maybe 1999), I bought a new pump from an MB dealer for $100.00. Came with the MB STAR on it. Dealer won't take core pumps w/o STAR. All of the WEB sellers of the brands you mentioned wanted more $$$ than the dealer.

This isn't the sort of job you want to do again in 6 months.

Go buy the pump and gasket from your local MB dealer.

My 2 cents.
