Re: mid 70s GM steering box (Farm Jeep?)
The v-8 box has the variable assist...little assist right off center, with greater assist the farther you turn the wheel, so it isn't squirrely on-road, and is easy to crank around off-road. The '76' does refer to the box design as well. If you get the aforementioned v-8 box from the Camaro/Firebird of the same vintage as your jeep, it should have the same fittings...it will be the 4 bolt...and it will have larger bearings/etc. inside it than the standard GM p/s boxes do (yes, I know they're not GM boxes). As for the standard versus sport suspension, not sure, I wasn't asked when I swapped mine in...I'd guess the sport suspension. All of 'em will bolt in like Brownbagg said. But, the box you're looking for is, unlike what he said, built sturdier than the standard ps box... As far as the safety of the quicker steering ratio goes, you can decide that...I've been very pleased with it on my 4" lifted CJ5.
