Didn't find any spacers under the tunnel on my '64. Will be putting the tunnel back on in a couple weeks, using a foam gasket kit from SOR. Looks like the spacers are to prevent over-squishing the foam gasket. Can anyone give me some dimensions on those spacers? Maybe I could fab or find a semi-appropriate replacement?
I think @ClemsonCruiser was where I saw the spacers in detail on his UNREAL correct 45 build
