Slim Jazz Bass Neck (Heel width listed as 63.8mm) would like to meet Sporty Rear Rout P Bass Body (Pocket width listed as 63mm) for a lovely fit at the heel. (No Scratchplates or Pickguards please)... and I realy don't want a c0ck up on the first date!   So any Basschat Luthiers, Budding Bass Builders or Woodworkers in South East London / Kent BR6 area-ish willing to take a look, assist or advise?... Please... Someone must be local and know-their-onions...
