S2 2001 Single Sided Swingarm from 916/996

Hi all.

I am new to the world of Ducati and I am about to undertake my first build of one.

Essentially I have an S4 with a destroyed engine that I recently purchased. I have been reading into some 916 model bikes and it appears there are crankcase differences relating to rear swingarm mounts.

On the S4R it would appear that there is a mount point on the engine case that has a bearing installed for the S4R swingarm.

If I was to fit a 748/916/996 type swingarm would I need to build my engine from a superbike block or does the ST4 / S4 916 block accept this type of swingarm?

Please excuse my potentially poor explanation . I think I know what I want to do but I am not sure I just described it well
