Was told to replace this and quoted $70. Part only $2.50 and just a few bolts, so figured I'd DIY. Bit confused as to where the actual rubber ring goes though. Does it get embedded in a slot in the mechanisim itself, or fit right up against the housing (as pictured in red below)? This is on a 1991 Honda Accord, SOHC 2.2l (in case it matters <g>).
