Exhaust hangers

[sokoloff]

The EPC calls for four of the rubber donut exhaust hangers for my 560SL, two of 124 492 00 44 and two of 107 492 00 44. The two 124 hangers go on the center muffler and the two 107 hangers go on the rear muffler. The 124 hangers are about $4 and the 107 hangers are about $12. As I understand it, there are hangers with a wire or chain inside, most likely the more expensive 107 ones. It looks to me like either one will work in either place. Am I correct about this and is there any reason other than price not to use the more expensive ones?

Another question is that I looked under my car this morning and there are five, not four hangers, three for the center muffler and two for the rear one. Anyone know why the discrepancy in the EPC?

The rear ones are about 2 times the size. Get the genuine OE do it once do it right.

The originals are expensive, but cheap if you consider that the replacements I had originally purchased lasted about 1/2 year.

Oh, there's no question that I'll be getting the OE ones. I was just curious about why two with the 124 number and two with the 107 number. I guess the ones with the wire/chain inside are really only absolutely necessary at the very rear.

Len:

I'm getting ready to replace my exhaust hangers. Did you end up, as suggested, with the hangers with the chain at the rear and the typical doughnut at the center? What did you do at the forward (5th) point?

Thanks,
Scott

Scott - I replaced all five of my hangers, using the ones with the chain in them only at the rear. I used the regular donut ones for the other three. The ones at the rear were a real bear for me to get on, but they eventually did go on.

Len,

I am looking at replacing my hangers too. But on a '72 350SL. Looking at Arizona ********, they say that the diamond shape units are interchangeable with the donuts. They also have hard and soft donuts.

The passenger side manifold has broken three times on may car, and in an attempt to correct this, amongst other things, I installed a non-standard clamp with webbing strips to provide some flexibility attached to the torque converter bolts (My 300D has something like this). But this was removed when the transmission out for resealing.

Do the OEM parts have a manufacturers name on the box? (Brake parts sometimes do) - The Arizona ******** aftermarket parts are very inexpensive!
I am sure I will buy OEM, but is interesting to see the price discrepancy!

EDIT: I checked under my car and there are supports in just two places - behind resonator and behind muffler. Both use donuts. The part number is 1074920082. In my trunk I had two spares - number is 1164920182. These look slightly smaller, but maybe it is just stretch. I have replaced the resonator support donuts and will probably piuck up a pair for the muffler and at same time have dealer check why the numbers are different.
