Moogle kit - a kit with 1.25x mods and 6.25x spacebar for keycap sets that don't have them
Tsangan kit - a kit with 1.5x mods and 7x spacebar for keycap sets that don't have them
Original dolch only came with 1.5x mods, so you'll need a moogle kit for most keyboards. Alternatively buy the exact replica from originativeco (when he sells them) which comes with all keycaps for all layouts.
