Hi guys.
Was all excited about my first trip to Wheels In Motion on saturday to cure my tyre destroying alignment problem

. So i was gutted that instead of sorting it all out, he told me to rebook when I've replaced the front wishbones and a snapped rear spring

. Still most places would have probably taken my money anyway and made the car worse! May as well take it off the road for a little while as it's also cambelt and rocker cover gasket time again. Anyway - have a few questions.
1. Rear spring - how easy is the job? Had a little ook through Mark DTMs guide and was suprised to see the shock coming off and subframe dropped

Is it not possible to get the blighter out with just spring compressors?
2. Any good source for the spring? Autovaux? Ebay? Do you have to change both sides at the same time? WIM guy said the other one looks much newer so was maybe already broken and changed by the previous owner.
3. I seem to get around 18 months - 2 years out of ebay-special wishbones. If i recall vaux are stupid money, but is there a happy medium? Prices seem to vary a fair bit on ebay, but are they all the same cheap parts, and if you choose to pay more are you just lining the pockets of a bolder ebayer who claims his wishbones are fantastic and 'not like all the other cheap tat on ebay'?
4. I remember discussion ages ago about looking for a source of quality bushes to rebush the bones (using BMW 5 series bushes maybe??). Was this ever resolved? Anyone got supplier/prices of good bushes, and will these really last much longer than those on the ebay special bones? Not really looking for hard poly bushes or owt like that.
5. Will do my cambelt myself again. Does anyone here lend/hire the locking kit out nowadays? Or did autovaux do it (though I want to get the kit from my local motor factors)?
6. Autovaux rocker cover gaskets gone one side in under a year I think - doh! So much for them being genuine. Could somebody remind me how much the genuine ones are again?

.
Any advice much appreciated. Cheers!
