Can I Swap my lift and axle from my 2nd gen to a 3rd gen?

Howdy folks, this is my first post on the 3rd gen side, lol! Built a few 2nd gen prerunners and thinking about picking up a 3rd gen

Here is my questions...

Can I use 4" spindles from a 2nd gen, 3" coil overs from a second gen, SPC UCA's from a 2nd gen for the front to get 7" lift?

Can I use a custom built ALCAN lift rear leaf pack from a 2nd gen for the rear?

I have a custom built axle that's on a 2nd gen right now with 4.30's I would like to use on my 3rd gen build. Will the axle be an easy swap?

On my 2nd gens I scrapped the 2 piece drive shafts and had custom 4" one piece all aluminum drive shafts made. Anyone have and issues running 4" driveshafts on a lifted 3rd gen?

Lastly, considering that the 3rd gen TRD Sports with AT trans come with high gears in the axles, has anyone run 37's with 4.30 gears on a 3rd gen?

Thanks in advance!

(Don't beat me up too bad I'm new to 3rd gens )
