6.0 lq4 / 4l60E in 98 tahoe 2dr 2wd

I hope this is in the right area and hope that it is ok since the motor is not an LS.
I have a 6.0 lq4 fromt a 01 yukon. The trans is a 4l60e from a 00-01 1500 truck 2wd.

I am thinking of swapping out the trans with a 4l80E but was curious if i do this if there are things that i need to take into consideration before i order any parts?
Mounts and so on.

I work at a salvage yard so i have access to alot of the parts if need be.

I am swapping out the Drive by wire to Drive by cable and swapping the ecm for a 00 ecm from a drive by cable truck.

This is as far as the decisions that i have made at this point.

Ok so i think i will be saying with the dbw. but Can anyone point me in the right direction for motor mount to put my lq4 in a 98 2wd tahoe. I would like to keep using the stock rubber frame mounts?

Thanks

These look real nice. Wish I had used them
