So is the original pickguard non-warmoth?
And just to be clear you're not replacing the bridge with a humbucking tele bridge right?
Is the body warmoth? If the body is warmoth and you're looking for a new pickguard, I'd probably just take some measurements and call Warmoth on Monday, about whether the humbucker telebridge cut out would work, or the vintage. Pickguards are easy to fix with a little sand paper.
