If you are looking to fit a GU patrol rear diff to the rear of you 80 or 105, we have a set of brackets that will suit the gu housing and alloy you to refit the factory cruiser 5 link.
The kit includes
Upper control arm brackets
Lower control arm brackets
Lower shock mounts
Rear panhard mount (standard height or raised)
You will need to take measurements from your stock diff to locate them on the patrol housing, although drawings are provided to assemble the brackets themselves.
