It depends on the bar. Stihl bars have the drive link count on them. I am guessing .325 chain. For Husqvarna 15" is 64dl 16" is 66dl. I would expect a 3005 bar to have less than a 3003 one for 16". I use the picco chain 55 for the 6 tooth spur and 56 works for the 7 tooth rim drive kit for a 16" called length genuine Stihl bar. Looks like it should work assuming you get the right gauge of drive links. https://www.ebay.com/itm/stihl-16-B...:U00AAOSwtYtc-xAg:sc:USPSPriority!26146!US!-1
