Trans swap ???

[cogsracing]

Hey out there.
Starting to swap out a trans in my 98 GTP.
I found a low mileage(wrecked rear end) 2003 supercharged Bonneville.
I have read some of the stickies about trans compatibility.
Just want to make sure that the Bonneville (it does have a 4T65E-HD per the other charts) will work in my 98 GTP. The cases appear to be different because of bosses and subframe mounts attach to the trans case in different places. As long as all of the bosses and attachment points for the 98 GTP are there, they should interchange.
Thanks for any feedback.

03 Bonne will not work. It's a special valve body etc for that one year.

Thanks for the info.
Also have my eye on 2 1998 supercharged Regals.
That should be a direct swap.
