800 series box has been around forever. its been around so long that they didn't even have a name for it. cause there was nothing else. i have one in my 66 belair that i upgraded to a jeep box for the better ratio.
afaik, the smaller and lighter (think fuel economy) and cheaper to produce, 605 box came out in the late 70's .

I think ill pick the junkyard for a box from a 93-94 grand cherokee. They have the 12.7:1 ratio and i can also use the u-jointed steering shaft from the same donor since it has the matching spline input shaft. I had a monte ss box on order but i canceled it. The monte ss input shaft wont take the u-jointed jeep steering shaft.
I learned from the articles that simply buying a box based on its advertised lock to lock turns can be misleading when looking at boxes for different cars. The lock to lock turns is also based on the pitman arm sweep angle. A vehicle with a longer installed sweep (jeep cherokee) will have advertised 3 turns for example. Put that box in a gbody with a shorter sweep and the turns are 2.5.
Ratio is what you need to pay attention to. SS Monte is 12.7:1 ratio. So is the Jeep Cherokee for instance. But if you look at specs on rock auto for instance, the ss monte spec will say 2.5. The grand cherokee will say 3. But theyre both 12.7:1 ratio boxes. Ratio between input and output shafts.

Picked up a 94 Grand Cherokee steering gear and shaft today. $70 total for both with tax, core??? And enviro fee 😑
its a high mileage unit so ill rebuild it before putting it in the wagon. I also have the correct pitman arm and hose adapters on order.

The headers in this car are wrapped to control heat under the hood. The original steering shaft with rag joint has the plastic heat shield. I'll be removing the original shaft and installing the Jeep Cherokee steering shaft with ujoints.
Am I ok "without" a heat shield on the Cherokee shaft or box?

i got a box on ebay i ts close ratio around 150 i never put it in because i put a solid u joint instead of rag joint and wow feels super tight got that at mikes montes
I have the Grand Cherokee steering shaft already fitted up. Although I'm going to rebuild the 800 box from the Grand Cherokee before the final install, I put it in the wagon to see how the ratio played out and compared to the stock 605 unit. The 605 went a little more than 2.75 lock to lock when installed in the car and about 3 full lock to lock when removed from the car. The Grand Cherokee box goes 3 full when on the bench and 2.25 when installed in the car.
