So... Can someone with a roadmaster classic or someone that has purchased the trunk mount with just the flat base plant get me some measurements? I need the dimensions of the top plate in which the trunk mounts to. I have a perfectly new trunk off of a Victory Cross Country that I think would look good on my cheiftain once i have it painted. Just don't know if I can make it work until I get a the dimensions of the base plate where the trunk bolts up. Any help with this would be awesome. Thank you in advance for any help with this!!
