Does the 88/89 linkage dog bone take a different bolt to mount the bone to the swingarm than a 86? Reason for asking is, I bought a houser -1 swingarm for my 86 and one of the bolt holes is a lot bigger than the other, it looks like it's either missing pieces or requires a bushing of some sort. The guy I got it from says I just need a 88/89 bolt, but I can't find anything that looks different than what I have. Thanks
