Default Front cradle has two spots for engine mounts

So I have a 2012 corvette chassis that I am building for a hotrod. I have the front cradle with two engine mounting points.
Does anyone know what the differences are?
One sets the engine back more, but probably uses different stands?
Here is what I'm looking at:

This is a guess but my suspicion is that its for RHD steering shaft clearance in say Aussie land.

If you are using the entire drive train will only have one choice as the rear cradle does only have one option.

Here is the pic of the rear cradle. Looks like a couple options?

Did the differential have different cases depending on Z06, ZR1, GS or base model?

Front, I don't know, but the 4 spots are on all C6's.

Rear, 09up has the 4 spots, GM shortened the torque tube about an inch.

The ZR case is more beefy than the Z06.

Bret Bradbury has an amazing write up on ZR d/t in C5 FI sticky section.

GM never produced the C6 in RHD, correct?

Those are all aftermarket conversions.

Here's my 05 removed for cleaning a few months ago for comparison.

I have an LSA crate engine I'm installing into the hotrod and want to use the cradle mounts if possible. Looks like the engine can set back and over to the passenger side about 1 1/2". This would clear the harmonic balancer to the steering rack of the LSA. I'll just get it in there and check it out. Thought maybe it was for a specific reason.

Yep not in my '11 GS didn't have choice I'm using a ZR1 diff and had to slot the diff mounts holes rearward in the cradle in order to install the ZR diff mounts which sit back about 10mm or perhaps I was already on the rears and needed to go back further.

Any plans for a diff cooler and what body are you using your '62? btw love that C7/C3 hood.

Only thing I don't like about JJ awesome C3 resto-mod is front transmission, I have a reasonable suspicion you are doing the rite thing .

Thanks,
For this project it is a 1958 Chevy Apache Pickup. The torque tube will need extended about 4"-8" depending on where I mount the engine.
Great company doing the torque tube right is Gamel Street Rods:
