Nice build bro! Is your Burb's 4 speed the original tranny? I've only seen a couple factory four speed Burbs, rare and cool to see!!! Looks like you and your family have a lot of fun with it, your pics make me jealous of the amount of space available in a Burb! (Also jealous of the beautiful area that you get to go wheelin in!!!) How do you like those extreme AT's so far?
