NSFW - Transplanting Model Features? (Weird to describe, see inside)

[FennecWF]

Okay, so here's about how it's going:
I have two separate UnityPackages for the CryptiaCurves VibaBun avatar.

ONE of them has a working Size Slider for the dick. The dick has no phys when hard.
ONE of them has working phys on the dick when hard. The Size Slider doesn't work.

I have absolutely no idea how to use Unity besides uploading, but I want the thing to function properly, so I need one of the WORKING features on the other avatar to complete it. I don't know what to do or if someone would be willing to assist me.

I have the unitypackages for both. Assistance is greatly appreciated. Thank you.

the better term is transferring btw, since "transplanting" usually sounds like ur tryna yoink a part off a model and stitch it onto another
