Help with brake lines over multiple years

[sportfish69]

I have a 69 GMC step side. I converted to front disc brakes using the complete front suspension and cross member from a 90 suburban.
Now it is time to run brake lines. I plan on using a manual Wilwood master cylinder. Inline tube has a manual front brake line set for a 73-80 mdl kit. Can anyone tell me if this will fit my situation?
Father son project on the 10 year plan for completion.

Thanks in advance.
