i bought some of these from e-bay, and i am in the process of fitting them.
they don't really fit all that well. the shank is too small for the max holes, and as mentioned above, too long for the rear.
it was a pain to trim them off a bit.
i'm working out the wiring now.
they do look better IMO though.
what i did in the rear, is from the blinker in used a zinc coated fender washer, a large rubber washer, then a rubber grommet to take up the space between the shank and the hole. then another rubber washer, another zinc flat, then the lock washer and nut.
in the front, the hole is smaller, so i left out the grommet. no trimming is required here.
i'm thinking the rubber washers are messing with the ground though. i'm going to remove the inner one.
i am having trouble getting the running light-blinker sorted out.
i can get running or blinker, but not both.
time to get the tester out i guess.
