looking to up grade to universal drive shafts for my xl does anyone know if these are good? and what would the purpose of reverse threads be for? here is the link check it out. http://myatomic.com/catalog/viewsku?sku=HBS61152&itemname=drive_shafts_savage_2_

if you have an xl these universal drive shafts are a down grade. sure the u joint will be smoother but the diameter of the dog bone part is quite a bit smaller. the left hand thread was used on the savage21 and 25 way back when the savage only came with 14mm hexes.
