5lug-6lug compatibility?

Recently had a accident(last night) fairly heavy damage to the front end of my truck(not entirely sure the details yet) but know of a 2007 2.7L 4x4 RC Manual Tran. in town that just went up for sale. I stopped to check it out, original owner, has had the frame and leafs replaced, well maintained(seemed like a trust worthy guy) all the work has been done at the dealer.
Truck has 295k miles on it (which worried me)
My truck 5lug RC Auto Tran. has 105k miles.
Questions are I know the motors are interchangeable, but how much else is?
Can I swap the tranys?
I know the suspension is different?
Any advice would be great, again I might not need to much for my 5lug, definitely will need radiator, both front quarter panels, and hood.
If I can get the 6lug for 4k think it would be worth it

 

Not sure, but I'll bump your thread.

If the other truck works why not drive it?

 

Thanks for the bump, I would definitely drive the new truck but I'm just wondering how long it's going to last before I'm taking everything from my 5lug to keep it going

 

Bump

Im thinking the 4x4 would have a different trany can anyone confirm this for me?
