I recently bought a 1980 Honda GL1100 Interstate, at least I think its a interstate, but anyway I was looking around on it today and found that the Rear Case has a BIG crack in it. At least I think thats what its called. It is the part that is to the left of the battery. What I was wondering is where do you find parts if at all for this year model bike? I have looked around some on the internet and havent been very successful. If anyone can help that would be great! Thanks, Albert
