    So, as some of you know, I stuffed the 9-7x into a tree like a goober Labor Day weekend. To replace it I got myself this 2003 Trailblazer 4.2 LS for stupid cheap. It's an oddly optioned truck. It's an LS with cloth. But it has a sunroof and OnStar. Something I haven't seen. I am in the process of finding an unlocked 2004+ radio so I can add my XM Tuner to it. It's got 171k now. The hood is rusty, but we have plenty of junkyards with good hoods.

    DISCLAIMER: Much of this is carry over from the 2005 9-7x, and while not complete yet, they are the mods that were already done to the Saab and will make their way to the TB.

    Nice. I would have to lift front or lower back since I hate rake, but it looks like a heck off a start

    Ay, same here! I've never noticed another LS spec'd exactly like mine before.
    Of course, leather seats, OnStar/HomeLink mirror and console, running boards, fog lights, and signal mirrors are easy enough to transplant from an LT/LTZ; but sunroof? Not so much.

    I've seen more than one Blazer with an aftermarket power sunroof. Not the prettiest thing in the world...

    Good luck!

    Isn't it fun to have the knowledge and parts to work and mod it?

    Is the 9-7x front stab bar bigger? I have a 5.3 parts 9-7x that I'll have to look at the bar. My LS sure doesn't handle like my Saab.

    Don't worry, that's the plan! I'm only going to level it and put slightly larger tires under it. Nothing drastic. I am in the process of designing skid plates for it. My roomie is a Jeep guru and wants nothing more than to build my TB for me.

    Yeah I've never seen one quite like it before. It's got the auto dimming rearview mirror too, which I kind of hate. That'll get swapped from the Saab which didn't have it. 02-04 leather seats are ugly IMO.

    As far as I know it shares the OEM GM Part # with that of the TBSS. I found this out by accident. I ordered sway bar bushings for a 2005 TB and they didn't fit. Low and behold, different part numbers. Different sized bar.

    Color matched the old mirrors from the 9-7x. Lookin' good.
