Need help converting d90 to d110

[kbzx35]

Hi all, I currently have the Rc4wd gelande ii and want to convert it to a d110. Just received the new chassis and have the extension coupler. Some other things I know I need are the rear lower links and the bearing for the coupler I emailed RC4wd for help and they replied back saying that they can't help which is unfortunate and honestly a bit disappointing. So does anyone know the sizes or Rc4wd part #s for the rear links and bearing? Also anything else I'm missing aside from the body? Any help is greatly appreciated thanks! Also if someone already posted this before then I apologize but I couldn't find anything.
