Traxxas rustler tires on arrma senton 3s

[Kimmy anne]

So today my BF bought some new traxxas rustler tires to go on his senton 3s blx. When we got home we discovered it didnt come with any combiner peices (hope I got that right) and the ones from the tires we have on it don't fit. I've googled what I part need but I cant find any good answers. Thank you in advance for any help.

You probably need a 14mm to 12mm hex
