Talking Engine Couplings?

ive dealt with this seller once before, and have used this particular couplers twice to make repairs. while they arent the same as the original, they will work with what you have there. he also makes black standard replacements. i must buy some more from him actually... used most what i bought up already.

depending on what screws are underneath and whether you have one or not, this pack contains a triangle drive bit, plus the tender engine coupling.
