Think you will be very lucky if Tom can fit you in. I waited almost 2 years to get a slot with him then out of blue he rang me and said he could do it as he had a spare day. Unfortunately it took slightly longer due to inner sill and behind rear arch liner on both sides needed welding. Must say though it was worth the wait. I did find a classic car restorers in west Yorkshire who would have done it for £250.
