My 1970 Jimmy 4x4 is getting an LS soon. Based on much research I am looking at picking up a fairly low mileage 2007-2010 HD Silverado with an LY6 and 4l80e from Copart or similar. Since I am getting the whole truck I am wondering what other parts I might salvage. Maybe I missed it but I couldn't find any other builds that used more parts. Also curious what is possible vs what is practical. The wife and neighbors will not like the carcass laying around long so I need to get everything off this truck I might want (now or in the future) before the tow truck takes it away. I have never tackled this large a project before so forgive my ignorance. I will likely be getting help so my limitations might not be a factor. Thanks for the suggestions in advance.
