I think that when a person wants some how-to advice, we should offer that advice (only if qualified) instead of going off on a Negative Nancy rant with our own personal (often unfounded) personal opinion!

On the other hand, you are encouraging him solely because the OD is "nice", without any regard for the MAJOR fabrication needed to install it. Pics below are typical mods needed to install a T5 in an F-1, which is a narrower and shorter transmission than the OD. That crossmember is
the major structural element of the frame, and supports the brake and clutch pedals among other things. The entire center section needs to be removed, best done with the cab off the truck or even on the bare frame so nothing gets out of alignment.
