>>8858852For MGs, pretty much every single kit before 2.0 except the G Gundams and Ball.
For RG, pretty much just the Gundam and the Zaku, they are the only ones I believe have no extra hands and they use that god awful 1/144 implementation of 3.0 hands
For HGs, anything pre-HGUC relaunch, which means anything pre-2000.
