Looking at the list above, it looks like they don't have any .063G bars at all. Don't see any 36" bars listed there either. the only bar I see over 28" is that one Stihl mount 3/8-.050G 32" bar...
I did find some other 32-36" bars using the "Part Chooser" utility linked to from the Weedeaterman site.
SV3U-3Q80HV is the 3/8-.063G 32" (105DL) Stihl mount bar. (Yellow spacers would be used for a Husky).
SV3U-3Q90HV is the 3/8-.063G 36" (114DL) Stihl mount bar. (Yellow spacers would be used for a Husky).
Are either (or both) of those last two bars available still?
