As I finally have some time to spend on the hyper, I can get to replacing the bits broken from the bash where we attempted backflips...
So I'm looking for the following:
87029 front aluminium suspension plate, front of diff housing

87030 front plastic suspension plate, rear of diff housing

(But not the metal one, the plastic/composite one will do)
And as I'm busy I may as well replace the parts on the rear as well:
87038 rear plastic suspension plate, front of diff housing

(once again not the metal one, the plastic/composite one will do)
87040 rear aluminium suspension plate, rear of diff housing

If you have any kicking around, let me know. Paypal preferred. Ta!
