I just happen to have the MOOG K3090 instruction sheet on my desk! It has tow different size washers. The smaller one goes to the front of the car, a larger one is on the rear. The larger one has "THIS SIDE TO FRONT" marked on it, but in this case front means toward the back of the car -- it's the "front" side of the bushing though (could be confusing without the diagram!). In any case, they are mounted like this:
Front of car ---)H)--
I had the same problem as Tom -- the left front bushing kept disentigrating for some reason. I was beginning to think the car had been in a wreck at one point or another and there was some subtle tweaking of the body, but apparently not. I can't figure out why the driver's side has this problem and the passenger side doesn't. But I haven't had a
The exhaust runs right by the front rubber. Some cars have a heat shield. I made one out of aluminum for my Hornet, it bolts onto the extra holes in the strut bushing mounting bracket. I also made another heat sheild that bolts to the 904 pan bolts and protects the coolant lines and speedo cable from exhaust heat.
But I wonder if I'm still cooking mine? I'll bring my temperature probe to work, and measure the bushing temperature after an hour's drive.
1963-69 TSMs show --)H(- 1970-72 shows same as above for one piece bushings, --)H)- for two piece. 1974-82 shows same as above for one piece bushings, --(H)- for two piece.
Shape of the rubber pieces is different between early and late two piece bushings. I don't have a 71 or 73 TSM (I'm also missing 1960, 68, 77, and 79 -- just in case anyone has extras. Other than that I have a complete set from 1955-83). >
I cannot find any correlation between the washer direction and car model or part number (except the super one, mine came with a sheet also).
The NAPA part I have on the Hornet now also came with a thin cup to place under the washer, on the mount, like some (good) shock mounting kits provide. It supports the base of the rubber. So this is yet another variation.
Whether one direction or another is "better" it seems that it's a matter of degree, and not right/wrong.
The short of it for me is, I'm not taking my car apart to change them :-)
