Hey Rizaa I do know that the dropout are perfectly aligned (I set them with my Park dropout alignment tools) so if you just put a slightly wider hub in there, and do the trigonometry, the out of parallel angle should be very small (I used to be able to do that math, but I am just too lazy now a days!)
I would put that 2 mm spacer back in, and just spread the rear with your thumbs, and Bob's your uncle!
