hi,
I've just rebuilt my front suspension/steering(and rear suspension - hit a large rock which f@@ked both up and broke two wheels!).
Anyway- I live in Meath and work in Dublin - If you need some advice you can PM me.
regarding your front end - control arms including bushing from GSF or OTTO are about 48inc vat, you probably just need new roll bar bushings. not sure about the subframe clean it up and it'll probably be ok- mine has some rust also, I imported mine about 18 months ago -I think the Brits use salt on their roads which encourages the rust?)
good luck with it!!
