SB standard or billet starter ?

Strange because there is not a lot of load on that part of the starter a lot of new ones do not have that end support ,i have shattered a couple through kickback but further up at the casing where the 2 bolts hold the stator on.
It is strange and a pain in the *** to get in and out due to it molded around the headers . it is a stroker motor but nothing crazy.
