Hi first time posting my daily driver is a 05 H2 with a 6.6L Duramax LBZ Diesel Engine and 6 speed Allison Transmission with Triple Lock Torque Converter - Stage V great ride love driving it but not loving my interior has anybody tried too changed out an 05 interior and put in a 09 ?

 

I think all the interiors are basically the same, the only difference is in the dash layout. My advice, go to a dealer and find the Hummer your after. Note the differences and then buy only the parts you need. I think your swap wont be as dramatic as you think. You might be better off going full custom, as you clearly did with your power train (nice by the way).
