Order of operations? '67 K20 Engine, Trans, T-case

[Duluth67]

Hello,

I am planning install the engine, trans, and Tcase (which are currently separated) in my '67 K20.
What order would you install the components? I do not have a vehicle lift, so I will be working on the garage floor ect.

283 V8- New clutch
Replacing the SM420 w/ SM465 (I have the 465 bellhousing)
Rockwell T221

My first thought was connect the engine to the trans out of the truck, hoist that setup in from the top, bolt in in ect., and connect the t-case from the bottom. Do you see a problem with this? Any other tips?

Should I anticipate shortening/ lengthening driveshafts after swapping the 1968 465/T221? Laying the DSs next to each other, it seems they are the same length. The 1968 T221 is not the same as the 1967 T221, different shift linkage at least.

Thanks,

Paul
