Shortened wiper motor

[tigerburns]

Is there any such thing as a shortened or smaller wiper motor (original option or aftermarket) for our trucks. More wanting to know for the 4-5-6 dashes. I’m looking to eventually cut out the ash tray and install the center a/c box and duct. The wiper motor seems to take up lots of space considering an a/c box, duct, radio strap and speaker are all supposed to be in the same space. (I won’t put the dash speaker back in but) it seems too little a space for all that to fit.

Any of you guys know of a smaller and better option?
