Do you really like the look of vintage robots but like the convenience and features of modern robots?
Maybe you really like the modern Diaclone Big Powered, but wish it could have scale-equivalent arms?
Or do you just think its really cool to take the arms off things and attach them to other things, simply because you can?
Well now you can do all of these things and more!
This piece allows G1 Ultra Magnus (bluish-green and white) or vintage Powered Convoy (red and black) arms to be attached to your modern Diaclone Big Powered GV or Big Powered IMS Version, using the exact same slidey socket mechanism present on all current Diabattles figures.
Oh yeah, and the best part is the clicky mechanism in the donor arm is maintained!
So you basically unscrew Ultra Magnus's trailer arms and reattach them to this piece. And then you can swap arms on Big Powered until your heart is content (or 'heart's content' depending on how you say it).
Note: Although this has been rigorously tested, there is always the possibility that there might be some sanding or application of acrylic required to obtain perfect functionality from this piece.
