Suburban quarter replacement

[HO455]

I did some searching and found some threads on lower quarter replacement but, they were all from 2014 or older and I am wondering if some new replacement panel has come to market. The photos show what I am having to repair.

One shop I talked to wants to use a bed side to replace everything from the glass down. I don't know all of the differences between trucks and Suburban, but I'm not sure this would save any labor over doing two lower quarter patch panels. Someone else said that a Blazer side would work well and again i don't know the differences.
Any help or guidance would be appreciated.
