M915a1 transmission problems

[reb87]

One of my m915a1 trucks just stopped driving a few years back and I’m finally getting around to fixing it. Got the transmission pulled tonight and found that whoever last worked on the truck ( I bought it on gov liquidation Topeka years ago) only installed the flex plate with the ring gear and none of the extra 4 flex plates that are supposed to be used. I was hauling corn and had hauled probably 10-20 loads weighing 80000 pounds. It’s shocking that it lived as long as it did but it really shredded the flex plate. The part number for the whole flex plate assy is 3031751 but when I search it I come up with prices around $20000. Can anyone tell me where I can find new flex plates or if there is a newer part that supersedes the original?

Can someone waterjet you a new one?

Or lazer. If all the plates are the same and you have a sample and material spec, most shops have the capability to duplicate your sample with out a drawing.
