What gauge and mount is that 16"?
Brad, that one on the bottom is a Poulan mount, the old A058. It is a 5/16" slot and will work on the small Husky bar studs ok. The oiler holes will not line up but you can probably deal with that by filing the adjster holes up into the bar groove and it will oil through the adjuster holes that way. Seems those older 16" bars didn't use the standard 60DL chain, more like 58 if I remember right.
The tail is a little bigger then the K095 mount but that might be good depending on the sprocket your running as the K095 tail is kinda small.
Here is a picture of a D176 mount on a Husky 350, the D176 is a later version of that bar pictured, see how it oils through the adjuster holes?
Here is how much room there is with a 3/8's chain and that tail size.
The bar above it if I'm not mistaken is the Roper mount used on the Sears sportster saws and it a 17". As you can see its a bit smaller tail and can be adapted likewise and is a 5/16" slot also.
