Disc brake upgrade catalyst

[Figuarus]

Well....

This happened last night.





So, I've decided to get the parts I need to get the brakes upgraded, and this front end rebuilt.

The question that I've wanted to know is this:

Will the 73-87 VAN spindles work for this plan, or do I need to stick to truck spindles? Can I use the spindles with my 63-66 ball joints and control arms?

I plan on keeping my manual steering for a bit until I can afford to swap in a power steering system. Can I use my 64 steering linkage with the updated spindles?

Thanks for the help guys
