Well a parts search through LKQ which is a national network of auto recyclers is one way to go.
The part 221 870 77 89 80 is actually221 870 77 89 88 and is the MB factory remanufactured part. It lists for $2000 and parts.com has it for about $1450. A brand new one is north of $3000.
If you have a LKQ affiliated bone yard do a part search use the par # 221 870 77 89 so it will show up on their interchange list. The MB reman parts usually do not show up on the interchange list.
