true there isnt a lot of clearance but it does fit.i have some nice stainless universals lined up and will give it the clearance it needs.Being a KB laser or 323 i imagine it would be mid 80's or even a little later.Ots amazing how close to size it is but i still have to make the mounts and turn down the rack ends..not hard really..will post the pics when done..still working on the other mods..my mate in taiwan is sending me some new seats over in my next container..cant wait
