Case study / pitch

I’m looking to do a credit pitch but have spent most of my time doing equity pitches and model focused work for equity - I’m trying to see how to approach it and already have an idea in mind. It’s a distressed bond and want to make the case for a partial wipeout of the debt with recovery value less than what it’s trading for. Does anyone have a sample case study / model that can share to see how to approach this? Would be very helpful
