Need power flow for my GT235

[Builder]

Dealer wants over $1,100 for all the parts. There's also a lot of confusion as to which one fits my '01 GT235 with 48"C" deck.

Anyone have access to a decent used one, or better yet, anyone know the part number?

I see a few here & there on CL or Ebay and can't be sure if they will fit.

Thanks
