Had to take my box to Dick to fix a leaky seal on the sector (cross) shaft. Since the pitman nut had to come off, might as well get the kit.
Pick up my box (manual) and the rest of the kit.

Directions are sparse, but plain enough. They do state to check EVERYTHING else on your steering system to assure that this isn't simply to cover some other problem up. 'Nuff said.

First thing is to mock it up and see where to drill the holes in the K-frame rail. Now, I don't know about your K-frame, but mine apparently is not a factory-perfect example, even though I had Firm Feel gusset and weld it up and check it. The k-frame does curve and the bracket is flat. Additionally, the k-frame flanges are not super-wide, so positioning the bracket to fit best is limited. This pic shows how the holes ended up where mine fit best, and even then the bracket required some massaging. Enough meat on the one near the edge, and the other one has barely enough on the other side for the washer on the bolt.

This is how the bolts look coming out the bottom side of the k-frame. Clearly the curvature is apparent here.

Here is where it gets interesting. After drilling the holes (I checked the locations twice), the curvature of the k-frame and the angle of the bracket with respect to the axis of the sector shaft combine make for a slight problem. The directions state that the bearing can be swiveled in the housing slightly to compensate for any slight lack of perpendicularity of the bracket to the sector shaft, but this looked a little extreme to me. So I had to massage the bracket a bit to get the correct angle. Additionally,I had to slot the holes slightly to get the sector shaft nut centered over the bearing.

My lack of brake or a decent vise (since my workbench has not built itself yet) necessitated the use of a couple pair of vise grips.

In this pic, you can see the curvature I attempted to put into the bracket to minimize the installation warping when torqued down onto the k-frame. Not pretty, but at least it's under the car.

By this point, my back was getting sore from all the vise grip pulling and tweaking, so I called it good and depended on the slight bearing race/bearing retainer sphericity (is that a word?) to adjust the bearing to perpendicularity to the sector shaft. You can still see the off-kilter of the bearing to the retainer. Fortunately, the bearing itself fits snugly on the sector shaft nut, so keeps itself aligned that way. I was able to check its fit fairly easily by rotating the inner race around the sector shaft nut before tightening the set screws to assure that there wasn't any off-axis load on the bearing.

Done and car back on its wheels. (Cotter pins have been installed where they were missing in earlier pics.) The support is slightly lower than the oil pan, about even with the small aftermarket skid plate on the k-frame. Not as low as the headers, but not nearly as far back either, so shouldn't be a worry. Set screws are facing aft to avoid being boogered up by rocks.

How does it drive? I don't know. About this time, my 6 year old fell off her scooter and was having a meltdown about needing a band-aid on a scrape that wasn't even bleeding. Another reason this car is 8 years in restoration... (I've got an 8 year old, too.)

Sorry, should have mentioned before: '72 Road Runner.

Thanks for posting this MoparMarq.

I must admit...this thing looks nothing like what I expected. Pictures are worth a thousand words.

I have a spare K member that I welded up several months back. I added the gussets to reinforce the steering box mounts, but have been lazy in doing the k member swap. This sounds like a decent alternative for many people.

Thanks for posting that. I was considering this as an upgrade option on my 72' charger plus k-member mods. I have a spare k-member and was going to weld and reinforce it with some FFI parts (fast ratio arm, Stage II box, lower control arm pins) to really help it out. By the discription and requirements of my car, this isn't the part for me. Still, very cool to have that option if your don't/can't pull your k-member.

599 ?

I think you are not understanding Ricks observations, the entire #ucking box moves .100+ " at the lower sector, not just the sector shaft by its self. When the center link only moves 6" +/- that amounts to a lot of drift in the steering. The sector support stops about 90% of the flex the box has at the sector..... These numbers are approximate depending on tire size and wheel alignment.

Every mopar product I have ever owned has had the box flex and some bearing slop, this fixes the problem with little modifications to the system. The offroad guys that have jeeps like mine are doing the same thing. It works and people want to argue with it. Tim

The rack systems dont really work well in a mopar, a few have tried, not many do the job right. Tim
