1991 F150 300ci five speed swap to a four speed
 

I have a 1991 f150 XLT lariat single cab short box with a 300 cubic inch straight 6 and I am wondering if I could swap out the Mazda 5 speed for the Borg Warner 4-speed? Just looking for insight on whether or not they would swap right out or if a new bellhousing will be needed & or if the drive shafts are the same length.

Thank you in advance.
