Can't find a neck ANYWHERE for a 2017 Fender American Professional 5 string J Bass body. Warmouth said they can't build one, and I can't find anything on Reverb, STRATosphere, etc. Started building this PartsCaster for my awesome son, not knowing how difficult it would be to find a neck that would fit. Ideally, we were hoping to find (or have built) a maple neck/fingerboard with black block inlay...but at this point, we just need to get something that will work. Thanks for your help!
