This may have already been discussed some where on this sight I'm new here. I'm looking at possibly purchasing a Colorado with a bad I5. I think it's 05 or 06. I have an 03 Trailblazer with a 5.3 which has a bad trans. What parts will work from the Trailblazer other than the obvious engine? Wa t to keep it somewhat simple and makesure it look like it came that way. Any info would be appreciated. In the meantime I'll keep reading on here to seethe what I can find out. Thank you in advance.
