Vintage Tele Neck & Gibson Scale

[daluqfam]

Does anyone know the reason when building a Tele one pc Vintage neck(skunk stripe), the options do allow Gibson scale?

Because that’s a vintage spec neck and it has all the options that are reasonably vintage correct.

I am guessing you mean do "not" allow? All conversion necks are Modern construction only.

Gibson and Baritone Scale Conversion replacement necks for Fender guitars

Warmoth conversion necks allow you to change the scale of your electric guitar from the standard Fender to scale to either Gibson or Baritone scale, without having to make any modifications to the body.

I think it probably comes down to demand and costs. I don't think many people would typically be in the market for a "vintage" Fender neck with a Gibson scale length.

Musikraft makes one.

You've got it turned around somehow:
You obviously choose the construction type first and "Gibson® Scale Conversion" is a modern construction variant, as @Scab Pickens already pointed out.

So, if you choose Gibson® Scale Conversion, as a modern construction it doesn't have a skunk stripe, and the options for fretboard wood do not allow "one-piece", because it's not possible.
