truck is all fixed still problems

[stan79chevy]

i just did a transmission, transfer case, front axle and rear axle swap and it all went good. except my speedo is way way off i had it pegged out at 100 and it felt like 50 or 60 ish. that is with tires that are only about 30 inches when i put the 33's back on it should be closer but not exact. the 2nd problem really bothers me. somehow my steering wheel is upside down. i have full turning abilitys and it drives straight and everything. can i pop the steering wheel off and put it on straight or do i have to go under there again and tighten this and loosen that. how hard is it to take off the steering wheel? is it splined to go on only 1 way?
i have to fix the steering wheel i cant stand it. as for the speedo can i put in a different box thing off another transfer case to fix that or what?

thanks
