70 c10 to Disc

[Nh4clo4]

OK I read the sticky on the options for drum to disc conversion.

I have a 70 C/10

Am I correct that if I want to use my crossmember, I can get 71-72 spindles and use 71-72 upper and lower ball joints on my existing A Arms?

Then I have to switch to the 71-2 Tie Rods and Pitman arm?

I would like to use as much of my stuff as possible.

Thanks
ED
