I'm thinking of getting a flush mounting plate/bezel for my 4003 like the Pickguardian one or similar (may make my own).

But a flush mounting plate will have 1cm less headroom for the height adjustment spring. See pic below. The dotted red line indicates the approx level of the underside of the flush mounting plate which appears to leave hardly any room for a spring. The existing spring is quite long and, even it can compress into that space, it leaves very little wiggle room for raising the pickup height.

Can someone who has installed a flush plate like this tell me if the original springs still work or did you need to use shorter springs?

Thanks for any input.
