PE buy-and-build case study for thesis

Hi guys, I'm currently searching / defining the topic of my upcoming master thesis. The overall topic will be "Value Creation in LBOs", but I would like to specify the topic a bit more towards the buy-and-build strategy: Does anyone know of a well-documented case I could pick as a case study for the thesis? Basically, I just need a deal where data of the target prior to the acquisition and of the combined company post LBO is available. Appreciate every hint! Thanks
