Hi mate,
It was tickenham garage just outside of bristol.
If you're not around this way then also check out mrclutch as think they cover quite a wide area, they also quoted £450 including parts.
If you would rather take it somewhere else and provide your own parts, go to this link and make an offer of £250, they will bite your hand off (it's what I did)
