Rear Radius Arms

[Luckyun]

Are rover metro/100 radius arms compatible with with mk1 and mk2 metro subframes? In fact are thier dimensions stub axle sizes and fixings any different?
I've noticed they look neater and are lighter.

As far as I am aware they are the same casting, so I can't imagine why they look neater and lighter? the only difference is the thread and nut on the end of the stub-axle, I'm told A-series hubs fit with no problem using the K-series nut.

The early mk1 Metro radius arm pivot shaft did have smaller finer diameter threads on the outside ends so if you have mk1 bits you might need mk2 spacers which don't come with radius arm repair kits.

As i have collected bits and pieces over the past year i have aquired 2 different radius arms one looks similar to a mini's arm (rounded not squared of in profile)

yes the early ones are round and the later ones are square. i noticed it on my coupe....different on each side!

one of the jobs I need to equalize.
