idler arm id help!!

I bought this at some point-- it was to be a new replacement for my 69 dart-- it does not look to be correct for that application.. I have looked at pictures in a moog book & it looks to be a k-7041 for b- body 68-70 & e body 70 cars--- can anyone assist in the id?
the #'s on it are 57302 usa-stamped in the arm, 3594--10536 stamped in the zerk surface.
Thanks Lawrence
