I'm installing my transgo hd2, sonnax super hold 4th and 'vette second servo and I'm confused on the servo part. Everyone says don't use 2 washers but what are these washers? I understand the shim part bc the shift kit talks about it. The sonnax servo came with a washer.... is this the one I don't use? If i use it does it go under the e-clip with the stock washer on the pin or does it go over it after the e-clip is on?
