Ok so initial inspection is complete:
The neck fits snugly with some fantastic grain on the maple, really glad I'm planning on a clear finish.
The Fender electronics I got fit in the selector plate which is good.
All the parts and screws look to be here.
The issue I have found is that the Fender pickups I have are too wide for the pickguard hole (not that big a problem) and the bridge plate hole (this is a bigger issue).
So I guess the question is.. do I modify the bridge plate or do I buy an aftermarket bridge plate? I'm thinking the angle I'd have to use to get the strings under the pickup magnets would be more angled then the cutout on the existing one or is this not really an issue?
Also the cavity doesn't exactly fit the bridge pickup so I guess I just take some wood off equally in either direction. Maybe I should resolve the issue with the bridge plate first...
