2007 1500 Classic with 4.3L v6,

For simplicity I went with a 4.3 out of an '05.. just want to get it done for now.. being from New England its been so nice to work on a rust free truck PITA to split a tranny from a locked up motor. Especially in my cramped space. I'm currently at a standstill as I didn't have a beefy enough...
