disk brake conversions

[my67chevytruck]

Ok, maybe i am not searching correctly but i cannot find a thread in the FAQ that details everything i need, so i am asking the experts. Can someone point me to a detailed thread or let me know what i need off my 72 parts truck.

I have a 67 that i am building for my son, i bought a 72 roller with disk brakes and 5-lug rear to do the conversion. I have heard soo many scenarios i would like to know exactly what i need to pull off the 72 and install on the 67. I know i will need the booster/master , brake lines/clips, spindles rotors calipers. center link, upper lower ball joints ( will buy new for install) all steering linkage. 67 has ps now. do i need the upper or lower control arms... any suggestions would be appreciated, i am still new to the 67-72's, but loving it thus far.

Is it better to do a complete crossmember swap. I would have to rent a cherry picker.....
Thanks in advance.
