Man. The things you gotta go through to find honest, low prices for the exact same part. Just did a little more scouring around the net and found that Amazon states the RU567 will not fit the Crossfire but the RU534 will for $235.44

Summit wants $289.97 for same part and these guys think it's worth $346.71!!!

But I go back to RockAuto, who are cheaper @ $179.99 and they show that RU567 (which seems to be indicated for M/B SLK32 AMG) is compatible (or the same) as RU534 (indicated for SRT6).

And now the guy I bought from on Ebay just lowered his price to $33.84.

What a Racket!
