K095 will work fine on a 10 series so long as there's an oiler passage from the adjuster holes to the bar groove. Some have it, and others can be modified to have it with a couple minutes of dremel work (with a reinforced cutting disc). BTDT. A095 is basically the same. Original mount for the Super E-Z Homelites.
D176 is Oregon's "multi fit" bar mount for the 10 series, most midsize/larger Poulans (306/245, 360, 3400-4000, 4200/5200, etc), early XL12 and XL700/800 series Homelites, Lombards, and others with 5/16" studs. Same mount but with a 3/8" slot is the D096/D196 for the later SXL-AO and XL900 series Homelites and the last generation of the bigger Poulans (6900/8500 and some of the late 2nd gen 4900/5400 saws).
