Fitting 4L60e behind SBC

[68LS1]

Hoping someone can confirm I am right track.
Planning to change from 200R4 to 4L60e when I install Holley Terminator X Stealth fuel injection.
Down here in Australia we have plenty of the LS version on the 4L60e & 4L65e, which use the 300mm torque convertor but this requires changes to flex plate and adapters to bolt to the SBC.
Or I can use an early bell housing, https://globaltransmissionparts.com/...l60e-24206579/ and swap out input shaft to 298mm version, and then the 298mm torque convertor should bolt straight up?
Transmission will be rebuilt, so will be torn down and a new convertor used.

Or is there a better plan?

thanks
