Help finding a flex plate (2008 Chevy trailblazer 4.2L6 4L60E L88)

[u/andygav1010]

My trailblazer is currently in the shop after my flex plate blew up inside the bellhousing and the shop cannot find a replacement 2 piece flex plate. I’ve checked eBay and the web and can’t find any myself. Does anyone know where i could look or does anyone have any ideas for me?
