Reusing Part of a Single Disk Clutch

Working on a 98 12v 5spd 4wd truck that broke the input shaft. Owner bought the truck with a SouthBend single disk clutch already installed around 90k miles, truck now has 220k miles. All highway driving mind you.

I know the flywheel is warped just by running my hand over the clutch mating surface, which is blue in color from heat. However, the clutch disk appears to be just fine with plenty of material left. The pressure plate also felt fine via the clutch petal inside the truck. Not sure how or what to visually inspect on the pressure plate.

Questions: Do all single disk pressure plates share the same bolt pattern to a 13" flywheel? SouthBend wants $350 and Valair is $230 for a flywheel. Valair is not sure about the bolt pattern being the same. I am waiting for the owner to measure existing SouthBend flywheel so Valair can verify fitment.
Am I safe with reusing this pressure plate and clutch if all was working perfectly before?
Will be replacing the throw out bearing, input shaft, and input shaft retainer housing also. Truck has upgraded hydraulics. Owner is on a budget.

You can have a machine shop surface the old flywheel. To my knowledge a 13" flywheel is a 13" flywheel besides the pilot bearing being a roller bearing on the sb and valar. Napa would have a 13" flywheel with 12 1/4 and 13" mounting holes just a needle bearing pilot.
They both originated from a luk brand clutch.

I have not had luck with facing a flywheel in the past. And would also like to keep with the roller bearing for the pilot.

I agree with you that it should bolt up, just asking if someone else has maybe done this before.
 
We used the Valair flywheel with SouthBend single disk clutch and pressure plate. All worked great together.

I received the flywheel from Valair very quickly!
