Couldn't verify that part number on the bushings. Ordered from cruiser outfitters who had some in stock. Probably the same damn ones but didn't want you to have to go though the trouble without knowing for sure.
So they came in. The number on the rubber is 1178/6. Here is a photo. Probably the same thing.No worries. The washer covers up the p/n on the ones on the rig here too.
I'm fairly certain they're the right ones...I want to say the rears have smaller studs than the front, but it's been almost a year since I did the work.
Report back, then I'll know what I have too.
