you live in Denton dont you? or near it anyway?
Where Crown Point North is, just a bit further up the road towrads Audenshaw/Guide Bridge, there a pub on the right called the Dog and Partridge, it's on the corner of the main road and Frederick street, turn into Frederick street and straight away on your left there's a garage.
The guy's called Ste, he's resonably priced (pretty cheap to be honest) and does a good job.
He took the piss with my car a while ago but thats only because i always go to him and for some reason he leaves mine to the end of the day then he never has time to do it. But if your a random customer he'll book you in and get in done for you.
go and see him anyway just to ask how much, take the parts with you and tell him what you want doing etc, he'll give you a price then and there.
let me know when you go to him
