Will not fit as is, I tried finding one for 82 xs 400 seca, which has same frame etc as yours, and had absolutely no luck (found one for over $200, way too much) ended up buying a welder and making my own. Worked out great, good learning as well and have a welding machine for the future, may make saddlebag racks this year. Bike is still in storage, can take a picture in a week or so if interested in how i built it.
