I got started on the assembly of the front suspension and ran into one more issue. The passenger lower ball joint was way worse than I thought, it easily pops out of its seat. The plan is to replace both lower ball joints but I have not ordered them yet. In Europe its not as simple in the US, if I ordered these today they would take about 3-4 weeks to arrive.
Luckily some old drum brakes came with the new k member and lower control arms so I could use the lower ball joint from that. Somehow, with a grinder cutting the heads off the bolts and an acetylene torch it took over an hour to free the ball joint and part it comes with. Very rusty stuff.
With this done I then learned that the holes are different sizes.. I guess drum brakes have smaller bolts? So my friend kindly let me borrow a 15mm drill to make it bigger. This is just a temporary solution so that the car can get four wheels on the ground and get to the chassis jig.
With this done it should now just be a matter of putting the parts together and the car will finally be a roller again!
