tranny swap

I plan to swap my motor and tranny, I have an 87 f250 4x4 and want to swap with a 86 f250 2 wheel drive both with 351 carb and c6s what i need to know is will this tranney bolt to my trasfer case or will it need to be modified ? I dont have the other truck yet so i cant just look but i do recall the tranny looking longer,
Thanks

The output shaft and the extension housing are different from 4WD to 2WD. You will have to swap the extension housing and the output shaft.

is this something that is done fairly easy? thanks

Hi... sorry for the delayed response. This is NOT easy. The entire tranny must be disassembled to replace the output shaft. This should definitely be done by a professional.... sorry. Where are you??:confused:
