i bought a new in box ST 2500 a few years back , the old owner added a backplate, because he apparently lost the orig backplate , he included the radial mount, which i'm not going to use. because i'm going with a standard mount.

the prob is that the backplate is for something else and hits the conecting rod, because its too long .

i went to tower hob and the part number checks out , but its the wrong part.

thanks
