Will Josh's 6263 Daytona caseback fit a 1652xx?

[freddy333]

Does anyone know if the caseback from Josh's 7750-powered 6263 (Dia 39mm x 12.5mm Thk)

will fit his 116520 (Dia 40mm x 13.5mm Thk)

The reason I ask is because the caseback on all 1165xx rep watches is wrong -- they all come with a beveled caseback similar to this one (though the width of the bevel may vary)

The caseback on gen Daytonas is completely flat across the back, similar to this (though 11652xx Daytonas are brushed instead of polished)

Here is a picture of the caseback on 1 of the Daytonas given as prizes to the winners of the Daytona 500 race (note that this is a picture of a gen 'Winner' caseback, not the well-known rep with a similar, but fake engraving on a beveled caseback). Gen 1165xx casebacks look like this, but without the engraving

I have 1 of these pre-Daytonas that Josh sells (Dia 37mm x 12.5mm Thk), which has the correct flat face, but its diameter is about 2mm's too small

Fitting one of these flat casebacks to a modern Daytona rep would not only improve the appearance of our 1165xx reps (since the caseback would look the same as the gen), but, more importantly, it would allow the watch to sit lower on your wrist, which helps to offset the slightly thicker case used for most of these reps.
