Help please.

I recently (last week) bought a 2002 Takara reissue of starscream, and everything was cool until I started transforming him. While doing this, once I moved his arms from their alt. mode position, they are ridiculously loose and swing readily by just tilting the figure. Looking closely, it's the black plastic rotating shoulder mounts that are not sitting properly in the red die cast torso section. Comparing to my other G1 seekers, this plastic peice appears to be too small. I've looked at the stamps and I'm pretty sure he's legit (not KO) and the rest of the figure is fine, but it left me wondering:

1) Does/has anyone else had this issue?

2) were there any really accurate KOs made of this figure?

or

2) does anyone have a fix for starscream with loose arms?

Any help appreciated
