Thanks Wattage - still looking for a neck. To describe my conundrum in a bit more detail, looks like I need a heel measurement of ~22-23 mm from the fretboard to the base of the neck for this to work with the bridge I'm using (22mm or so seems to be the 'standard' Fender depth and also seems to be used on -at least some- Affinity Squiers.)
The existing neck (that I can't use) has a measurement of about 25mm - so any of that same depth will be a no-go Thanks!
