Well, stripped suspension down today. Few seized bolts slowed work down a bit but all stripped in the end. Need to take both arms to a garage now to get the drum taken off one and the disc setup swapped off the bent one onto the good one. I would do it myself but bolts are way to tight and my airguns nowhere near powerful enough.
Heres a pic of the two, new and old. You can see the bush bent and the actual arm kinked....
Also got a new rear door. Theres a couple of small dents in it which need sorting but its the right colour which saved me alot of hassle...
