Running a two piece rear main seal crank in a 1 piece rear main seal block

Running a two piece rear main seal crank in a 1 piece rear main seal block
The tile pretty much says it, what all is required to convert to a two piece rear main seal crank from 1 piece?
My understanding is that I will have to:
Get a seal converter/assembly (bolt on, no machining required?)
Get a neutral balanced flywheel/flex-plate to replace the one piece one I currently have.
And thats it? That seems too easy...

Why would you want to downgrade to the two piece main seal?

As mentioned you can get the rear seal adaptor for either for either the early pan or the late pan, I prefer the late pan as you can use the one piece oil pan gasket from GM = no leaks.
Also you will need an alignment mandrel to locate the seal adaptor.

I have used a lot of the later one piece rear seal blocks and used a 2 piece rear seal crank.

You want the later 1-piece rear seal block because the machining is much more accurate than any 70's block.
Not that a 70's block can't be corrected by a very competent machine shop, but you will pay dearly for that.
The better choice then is a DART block.
