LQ4 to Turbo 350 Flexplate mods - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am getting ready for my 6.0 LQ4 72 K10 swap. Engine is a 2002 and has the flat flexplate.
Does anyone have a picture or diagram of the elongated holes required to bolt the convertor of the turbo 350 to the LQ4? Thanks

I took off the flex plate and held it to the converter with center adapter. It's maybe 1/8 to 3/8s off. I used a 5/8 drill bit and elongated the holes and cleaned them up.
