I recommend using a screw map found on the Web, or even creating one from scratch, so you can easily remember exactly what length of screw goes into which hole. I printed out such a map for my very screwy Stampede (ba-dum TISSSHHHH), taped it to a sheet of cardboard, then actually inserted the screws into their corresponding positions on the cardboard map.

Also, if the Jyn Erso is the OP's proposal for a first blaster mod project, I would rather start the modding experience with a simpler Stryfe if available.
