    Drive shaft is the same. Trans crossmember is probably ok unless you're doing dual exhaust. You need the reinforcing "belly bar" under the engine to do it right, but it's not technically required. The C4 bellhousing you have will work as long as your six is a 250. If it's a 200 or 170 you need to at least change the bellhousing. Frame stands, engine mounts, of course suitable accessory brackets, and someone else can confirm this but I believe the V8 and I6 radiators are different.

    There's two C4 crossmembers. One has a single "hump" for exhaust clearance the other is clearanced on both sides. You might not NEED the double-hump crossmember to run duals but I'm not sure how you'd do it otherwise. The "belly bar" is just extra bolt-in crossmember that runs underneath the engine on V8 cars. Like the shock tower braces, you can do without it, but Ford saw fit to include that reinforcement on a car that they pinched every single penny building, so it's probably a good idea.

    As for the radiator, you can probably make the I6 one work, I've never really looked at one though. The V8 radiator has the lower hose fitting on the driver's side and the upper one opposite from it on the passenger side. If that's how it is on the one you have, it ought to work. As for actually cooling the engine efficiently I can't say.

    There's alot of threads about the I6 radiators for V8 cars on here. Many believe the 250 radiator will get you by with a 302, and I believe the smaller I6's used a different radiator. No stoning if I'm wrong...
    If you go aftermarket radiator ppl recommend Champion brand for our cars. Some have argued that a decent 2-core aluminum will cool better than the 3-core brass. The location of the lower hose opening is something to look out for.

    I'm sure someone here would have the crossmember, belly bar, frame stands, anything you need. Could post a want ad in the classifieds. And if by "Craig" you happen to mean Craig Selvey, he'd be a good man to ask about it.

    Needs a V8 throttle cable and kickdown linkage too, no?
    If planning on headers, might need to swap from column to floor shift.. Or at least jerry-rig it for now

    The 6 cylinder throttle cable will work, it just needs a little mod. I've seen it done on one of Wilburs cars

    Mine used to have the 6 cyl throttle cable too so I know that can work, but you may have a point on that kickdown rod. Easily remedied with the Lokar cable kit though.

    I drove mine for a few hundred miles with the belly bar in the trunk. The car stayed in one piece.

    +1 for lokar cable for kickdown. Was a pretty easy setup
