What is the difference in the bar mount on a Poulan 330 v/s 3400

[Cut4fun]

I am looking for a 16" bar and chain 7/32" 60dl for the PP330. But I found a bar + chain for a poulan 3400. Chains are the same, but what is the difference in the bar mount? From just looking at the pits I dont see the difference. It doesnt have the PP 330 listed for the bar. hmmmm.

Found the stuff on acres site. 8.2mm compared to 8mm on the stud slot. Oblong on the ajuster hole on 3400 and circle on 330. I just wonder will it swap.

Tm , like you said the oil holes are questionable . I'll bet Marco and Stumper will know .
