Yes, you need to measure the release bearing for the new stackup dimensions. You might be lucky and still be in spec, but likely it will change enough. The flywheel changes and that may move the pressure plate fingers to bearing face fore or aft. Since you are already "disassembled" during the change, it is just a few steps to check it. If it currently shifts properly, check the air gap now since you know that works.
Check it. That is one of thoes if you check it it will be good but if you don't you won't know it's bad until it is all back together.
Getting ready to do the swap, I did have another question. I realize that the hydraulic clutch lines are threaded through a hole in the bellhousing. That means I will have to undo the hydraulic clutch line. I wanted to avoid having to bleed it again but I don't think there is any other way to do it. I would have to remove the hydraulic throw out bearing and lines along with the bellhousing / engine right?
I'm guessing I have to remove the transmission still and then install the bearing and trans to the engine outside the vehicle. I'm trying to avoid having to go that route
