    Bought an 85 Jimmy, bone-stock. Definitely not a gearhead yet, but trying to learn as I go. I am looking for original spec info on my truck. All I know for sure is that it has a 305 w/ Rochester 4bbl and auto hubs, and is fun fun fun. Also looking for takers on a day trip May 3rd, near Denver.

    Notes:
    The 1985 Blazers had much wider body color panel between upper, and lower grilles, and the grilles had only a single horizontal bar intersected by seven vertical bars. The headlight housing had more of a vertical look than last year's, although the rectangular lamps were stacked atop each other again. An amber-colored parking lamp was standard on the bottom, but when halogen high-beams were ordered, the parking lamps moved behind the lower grille.

    Blazers featured a steel half-cab with an integral roll bar built into the steel front compartment roof and lock pillar structures.

    Lifted straight from the specifications page.

    Thanks Rusty, but I'm actually trying to find a way to figure out what T-case I'm running, as well as diff info (gearing and manufacturer) and axle stuff. I really do love this truck, but I hardly know her. That's good at the bar, bad in the garage... /forums/images/graemlins/thumb.gif

    While I have it posted, any ideas on where to find original brochure and old magazine reviews of the 85 Jimmy/Blazer?

    to know what options ur rig came with, you might check the manufacturer's label inside the glove box... all kinds of factoids about your rig in there...
