71-72 k-10 on 2010 sierra 1500 frame

[Will1994]

Hello, new to the forum. Had a question for you all. I currently am in the market for a 69-72 4x4 but want something i can take anywhere comfortably. Our family farm is located near an old junkyard that recently got a 2010 gmc max 4x4 extended cab truck in that had been in a rollover. It has a 6.0 ls motor z71 package and 82k miles. The frame appears to be straight. My question is, if i was able to get the rollover gmc truck at a fair price, would it be worth it to take a 69-72 body and stick it on? Or would the hassle be more than a beginner could handle. I am pretty mechanically savvy and my dad is a very knowledgeable diesel mechanic who might be willing to help a bit. I am very new to classics but have been in the market for a while, just couldn’t find the exact info i needed. Any advice helps. Thank you
