1970 c20 disc brake swap

[sim]

hello,

been trying to figure out if this can work.

1977 disc brake spindle from a g30, I replaced the "big disc" with a normal one
had to change upper and lower ball joint
longer hydraulic hose

everything works to this point. spindle is mounted and moves freely.

the point where I am a little bit curious is the steering. my 70 c20 got 5/8" tie rods (if i´m right?)
the van spindle asks for a 11/16" tie rod.

Is there any other solution than buying this super expensive hotchkis tie rod adapter sleeves where you can connect a 11/16 tie rod to a 5/8.

remember that I´m from Europe. So shipping heavy and big parts like a spindle is very expensive.
