Went to install new shocks and of course they don't fit. Posting pix of mount and old shock. Can someone point to where I might find bushings that would fit, guessing they are 14mm? All I'm finding are ones shipped from china.
Thx much!

drill them out? or swap the rubber bushings. most aftermarket shocks come with multiple sized bushings. what are those?

LMS

Those are koni's and the bushings have been in there for years. I was able to get one halfway out, but then thought that someone might want these old dogs.
The rfy's didn't come with 14mm, just my luck.

Awesome, nice find! I searched that site but didn't use the correct key word.
Thanks!

I might have 14mm bushings for RFY's in stock. I'm not actively supporting that hardware lately, so I'd have to look, but I had a ton of stuff at one point.

The kit arrived and well, they do not work like I thought. One would assume that the cheesy plastic inserts are 14mm? Nope, inside diameter of the rubber bushing is 14mm, the largest plastic sleeve, probably 12. Does anyone see an issue with installing these with no plastic sleeves as the rubber bushing slides on perfectly?
thx.

I wouldn't worry about the rubber bushings on the shock mounts being without plastic inserts. They just dampen the shock itself a bit. Grease it up and install it.  My Hagon's only have rubber bushes and they work great.
