Jon is of course right. The trailing arms are same as Type 1 and will take beetle link pins. The whole type 1 king and link pin assembly will go straight on the arms. This will both lower and narrow the car significantly. You will also need Type 1 outer tie rod ends. The main beam is type 1 (and directly interchangeable) but the CB has some strengtheners around the bump stops.
Most people are trying to get the standard “high” front stubs for their CBs. If you have a set of stubs, and perhaps a beam, for sale they should be quite popular.
