I recently bought a set of mufflers from an 87 XVZ 1300 and wanted to swap them onto my 83. When I tried to install I noticed the brackets on the mufflers are different but the muffler itself seems to be identical. What I'm wondering now is whether I could the change the rear peg brackets and replace them with passenger boards from an 87 to make this work or do I have to go the slice and dice route. I want to thank you all in advance, I'm still learning about the First Gens and you guys are an invaluable resource. Thank you.
