I've ended up with an RRC and my S3 has gone to a new home. I've got my V8 now and it was easier than a conversion! Some lad in Bristol bought all the conversion bits so look out for him asking some questions on here (I directed him as such).
I've still got a rear safari door left if anyone wants it for free? Its in Swansea and has a few crusty bits but otherwise ok. Spare wheel mount, glass good, no real dents that I can see. No key for the lock.
cheers
