Ive got an Ace +4 on an 01 and want to move it to an 05 DS. My question is will an 01 fit an 05. They said something about a rear shock bolt. Has anyone done this?

 

If you swapping the 01 whole assembly to the 05 all you should have to do is change the upper bearings/bushings in the swingarm.
If you are going to swap just the swingarm you will need upper swingarm bearings/bushings, brake caliper mount, brake line, lower shock bushings, lower shock bolt, chain, and plastic chain guide and plastic skid plates if you are using them.

 

Thanks
