Please inspect pictures closely as yours should look just like these as they used this type for a number of years and all the other types of trim arms look quite different (note that this style does not have a rigid external trim line running the lenght of the cylinder like the post-1982 models have)
Sometimes there is obvious damage to the bearings and I’ll usually note that when that is the case
This is the old style that uses the 2-piece rear oil seal
