Is it just the crank to bar stud spacing? For example my ps5100s 18" takes 64 dl instead of 68. My 372xp 20" is 72 dl but if I put it on the partner s65 theres to many dl's. So my only guess is space between crank and bar studs. Although 2nd guess would be small vs large bar mount? I've never looked into it before cause I usually buy bars for the saw and thats what it runs. Now I thought the s65 was a large mount. The 20" cannon bar with 72 dl's will fit but will just barely tighten up. Whats the correct answer?
