Hi everyone in Spiderland, I would like to ask a question about the side washers on the rear mount on the 105 gearbox. Mine are missing and I have the gearbox out now. I am replacing the rear mount bushing and would like to know what is the size and material of the side washers? I have the parts catalogue which just shows a washer and no details about the size and material. I have a box of bits and pieces and there are two large rubber bushes in it. Are these the ones that go on either side of the bushing? Any guidance would be appreciated.
