The first pic shows the main hoop connections to the frame. Also integral with the hoop bracket is the outer seat belt anchor. The inner seat belt anchor is also shown. It too is bolted to the frame.
The second picture shows the layout of the front brace. It doesn't rise above the height of the seat, so it won't be hard to enter or exit the vehicle.
The third pic is taken looking forward from the trunk area. It shows the rear braces positioned inboard of the wheel tubs enough for the interior work to be done, and also the shoulder belt anchor plates. Right now, I'm planning on having the rear bulkhead mounted directly in back of the rear brace anchor points.
Well, it's been a while since I last posted, (10 months!) so I have a lot to catch up on.
After finishing up the steering, I sent the Willys off to the street rod shop (Posies Rods and Customs) for the rollbar fabrication and installation and some body work.
First, they fabricated the rollbar based upon my mock-up and their judgement on the best way to do it.
The first picture shows the finished rollbar as seen from the front. It consists of a main hoop that sits behind the seats, and a crossbar just above seat height. There's enough space that the rear window is not obstructed, and that there's enough room for the interior panels.
The second and third pics shows the bracing from the crossbar down to the frame in the rear. Also seen is a secondary horizontal brace that will be used for mounting the seat belt retractors. More on the seat belts later...Also shown is the forward brace. All connecting points of the rollbar are bolted directly to the frame. The rollbar was actually fabricated in pieces so that it can be removed. It will be a big help when it comes time to paint and do the interior.
The first picture shows the entire steering linkage from the connection to the steering column on the right to the connection to the rack on the left. All of the joints are in phase and ready to be installed.
The second picture shows finished installation.
Now that the steering column is located, I can go ahead and mock-up the steering linkage. I ordered the u-joints from Borgeson: (1) combination u-joint and vibration reducer to connect to the steering column, (1) 9/16-26 x 3/4-36 u-joint to connect to the Unisteer rack, and (1) 3/4-36 u-joint for the middle. At first I thought that I could get away with just two joints, but the geometry wasn't right. So I had to go with 3 joints. Anything over 2 joints, and an intermediate support is required.
The first picture shows the mock-up of the system using 3/4" wood dowels. This worked well, because I could cut and try until I got a good layout. Once I was sure that everything fit, I ordered up the real 3/4-36 splined shafts from Borgeson as seen in the second picture.
In order to brace the hoop, there will be a horizontal bar located about seat height between the hoop uprights. Also, there will be bracing that extends down and to the rear from the horizontal bar to the frame rails. In addition, there will be front braces from the hoop down towards the floor along the side of the seats. These front braces will "shadow" the seat, so there will be no need for a swing out style brace. Again, when I bring the car in to have the bar fabricated, I will be able to show what I want. From there, the layout can be refined to allow for interior upholstery and overall fit-up.
