wait, you got a shorty? the shorty is not the same as the full length. the info i sent you in the pm is for a fully length. the shorty requires cutting and sewing of a new cover, not wrapping and stapling like the full length.
edit: just saw in another thread that you do have a shorty. i can recover it for you if you want. i've done a couple.
one i did in black vinyl and suede:
one in grey cloth w/pocket:
