Here is the Stihl mount 18", 3/8", .050 http://www.weedeaterman.com/product_p/sv3u-0q45hv.htm
Im not seeing a Husky large mount 18", 3/8", .050 on weedeaterman.com right now.
The Stihl and Husky large mount bars are the same... the only difference is the Stihl mount has a 12.3mm bar stud slot and the Husky large mount has a 9.5mm bar stud slot.
If you cant find a spacer to make the Stihl mount work on a Husky get with 'Homelite410' here on the site and he can probably help you out, he makes them.
Thanks for your help BigFir..
