Official Fix-Up Thread

If you mean swapping at the bicep, then unfortunately no. Plus the UE arms from the biceps down are the same as any double jointed larger arms (eg Cena, Triple H, Warrior....) so they don't need to be UE.

What I've found is the peg length of the shoulder balls for single jointed HHH style arms, is too long for the socket part of these new double jointed HHH arms. Meaning you'll have a gap between the older shoulders and newer double jointed biceps.
Even if you cut down the mushroom caps of the older elite HHH shoulders, it'll still be too long. This is because the length of the stem part of the peg between the shoulder and the mushroom cap/peg tip, is too long. You'd need to drill into the socket to make it deeper, which will then need the fit tightening with sculpt or something or there'll be a risk of it coming loose again.


But for info - the smaller double jointed arms can be swapped onto smaller elite shoulders for single jointed arms, all that is needed usually is to cut the mushroom cap/peg tip down to a narrow tip.
