Default C3-Jeep Steering Gear Conversion

I have finnaly finished the VetteMOD version of the Jeep steering gear conversion. I beleve this could be done for much less than the kits out there and this modification is stronger AND is a bolt on conversion. The only thing missing is the drawings for the modification to the Jeep gear. But, guess what? The drawings are available in the download section! Any machine shop could modify this box for less than $100.

The pitman arm used is the 73-76 Chevelle arm #7814221. Call a local salvage yard, I'm sure they can find one for you. This is also a bolt on.

I am also using the 3 original Vette mounting holes but using 7/16-20 x 5 1/2 inch long grade 8 bolts. These are available from any fastener supply or places like McMaster-Carr.

The only other thing you will need is (4) 12mm x 40mm long bolts to attach the plates to the Jeep gear and the plates that can be made from the drawing in our download section. Oh, and (4) 1/2 inch ID x 1/2 long spacers.

When does the sale start? Looking good! Much better than how corvettesteering has the additional holes drilled with some actually intersecting. Spacers look a whole lot better too than those ugly strips they use.

No kit, but that's the beauty of VetteMOD. I will post drawings and anyone can take those to a machine shop and have them made.

Here are the hole dimensioned for the Jeep steering gear and adapter plates. The 2 adapter plates are 1/2 thick steel with clearance holes for the 12mm Jeep bolts and 3 holes tapped for 7/16-20 bolts.

I will put this drawing and a drawing for the adapter plates in the download section once I have verified the installation.

Yes, that is a better setup that what Tom includes in the set. Larry, where was this drawing about 2 months ago? I thought briefly about trying to come up with something better but then I just went with what I had...

1/2" think by how wide? 1"?

I might pick up the steel soon

All that I really need to make it is some drill bits and taps

Seems simple enough

Looks real good - a lot better than the Corvette Steering setup. What is the reason for using the 7/16 bolts? Also what are the reasons for using the Chevelle pitman arm rather than the stock Jeep? I'll be following this one!

The 1/2" peice is 1 5/16" wide.

I used 7/16 gr 8 bolts because they are stronger and I will be able to get a tight fit in the frame holes. This will insure the steering gear dosen't move in relation to the frame. I may even use a longer bolt in one or two of the 4 bolts that attaches the plates to the gear so that it is threaded into the frame.

I didn't use the Jeep arm because the indexing flats on the spline cause it to be mounted at an angle. The Chevelle 73-up pitman arm is a bolt on and is approximately the same center to center distance as the original Vette arm. I may have found a source for them.
