97XJ I6 Swap into 98 Wrangler

Didn't know where to post this, but I'd rather get input from people on naxja than another site... I don't need to hear about how hard, or not hard swapping a 97 XJ I6 into a 98 Wrangler that has a 4cyl is, its going to happen regardless.

Situation:
98 Wrangler 4cyl Manual with blown motor. The motor has been removed.
We are acquiring a I6 out of a 97 XJ with full harness and ECU.
I have a 23 spline shaft for the t-case already.
Not worried about drive shaft lengths at this time...

But I do have a couple questions.

I am assuming all I need to do is remove stock motor mounts and weld in new ones, correct?
I also need to replace transmission with something that will bolt to I6, but once that is done and I have the shaft in the t-case, the t-case should bolt right up correct?

I know this has been done so I'm hoping to hear from those that have done it, thanks!

dont forget the radiator and exhaust.... may need to be changed.

Thanks, yes they will be, forgot to mention that, my biggest concerns is the motor/trans/tcase/harness on this project.
