[Healeys] Trunk latch ???

[Alan Grossman]

Hi,
Still trying to improve a few things on the '58 BN4 I acquired recently.
So the car came with a new trunk w/strip, that appears to be correct. I glued
it to the lid, big hump to the outside (per moss catalog) and as expected I
need to rework the latch/strike relationship.

First, what are the correct machine screws to attach latch to lid? Head shape,
diameter, etc. The 1/4 20 bolts in there now are a real pain, can barely get
an open end wrench on the heads.
Next, I am using some putty stuck to the strike to try and dial things in,
anybody have any suggestions for the easy way to make this work? It seems
clear that I will need to make some shims, any suggestions on what thickness
to start with?

Hope I am being clear, and thanks in advance
Cheers, Alan
