Need help with a 17 inch iMac G4 repair

I recently bought a really cheap 17inch iMac G4 with 1GHz PowerPC G4 CPU, 1GB Ram, 75 GB HDD

I’m planning on buying a VGA DVI LCD Driver Controller Board Kit for LM171W02(TL)(B2) 1440X900 HD-MI and a Mac mini in order to use an updated system. I was under the impression that this was the correct controller board, but I am now seeing conflicting sources that say I need a LM171W02-A4 board which I am having more trouble finding. Does anyone with experience with a G4 have any advice (and would you be able to link me to any guides or sources that you’re using)
