1970 c20 disc brake swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

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.

Would these work for you?

Really what are the odds that we would both be in the process of doing the same thing on a c20. I pulled up the forum, because I couldn't remember how the steering went.

have a machine shop open the taper in the drag link to run tie rods off the 77

Haha, even the same name!

Thank you all. I've ordered the hotchkis tie rod adapters.
I'll let you know if it works.

It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar..... *Cubic inches is like Indiana Jones with a cheap pistol.*
