I have made some more progress on the front cross-member and double wishbone conversion. The lower control arm mounts are now finished.
Once I had worked out the control arm pivot positions I moved the pieces I had made previously onto the bench to get everything measured up and square. I then tack welded some scrap metal to them to hold them in place.
Then I had to position it in the car in the correction spot and take some measurements for the tube required to join it together.
Then with a bunch of tube notching, these are very short so I had to do a complete cut notching two pieces in one go. Usually I do one end at a time to the hole saw is not working so hard.
These then join to the parts I had made previously which bolt into the factory front cross-members mounts on the chassis rails.
I then tacked it all together on the car before taking it back out so I could weld it on the bench.
I also added some captive nuts to make adjustments to the geometry easier.
Even though I will be adding to these pieces later I decided to cold gal them to keep the surface rust away. I hate cleaning off surface rust.
Back on the car.
The rod ends will be mounted horizontally with spacers or varying thickness above and below. This allows me to change the inner pivot height over a reasonable range to tune the camber gain and roll center to my liking.
Next job will be the upper control arm mounts.
