I think the editing time period has already lapsed for your post but you'd probably get more responses if you would have made '2010 to 2012 Gulfstream Montaj' as your title rather than 'Odd Request' you'd get more folks looking at your post. Keep that in mind for another post - be specific in your title. Hope you find one in your area.
There's also a Gulf Stream owner's section on this forum - perhaps do a search in that forum.
