Bought a 2022 2500 At4 with a Duramax, trying to fit with a duramag aluminum service body. 
given the nature of current material markets and lead times, wait for a new model service body is 24 weeks…. I m hoping to get this into shape for work sooner. I found a Newley made 2022 service body but it’s made for model year up to 2019. My question is, will the bolt pattern work for the service body or will it not match up ?
