67swb build

[kanuck]

well time to make some decisions on which way to go.....I think I found the parts needed to do what I want, but need some advice. I found a private junk yard here locally, (2 brothers 20 year 10 acre back yard collection of a hundred or so vehicles) and they have about 12 '67 to '72 trucks laying around with very little sheetmetal left any good, but lots of other pieces. I found two trucks with 5 lug disc brake set ups and a six lug truck with power steering intact. Also a '79 heavy half swb with complete front suspension intact and 4-5 lug wide rally rims with some trim left on them.
So the questions are for up grading my 1967:

1) Use the spindles and A arm from the 71/72 truck to get disc brakes or use the complete cross member from the '79? End up with 5 lug front both ways. If I understand correctly I need to use the A arms and spindle from the '71/'72 but they will bolt onto the '67 directly?

2) I presume I should take the power brake booster from the donor truck and add a new master cylinder, but will this bolt directly onto my '67 fire wall?

3) Can I just change axles in the rear to complete my conversion to 5 lug at the rear? Has standard truck 12 bolt with 6 lug in now.

4)Do I have to do some modification on frame rail of my '67 non power steering truck to add the power steering box off of a '68/'69 six lug truck, and can I keep my same steering column or is it worth while to up grade the column as well?

I do plan on buying new rotors, calipers and brake lines to complete the conversions and have a reliable system.
Is there anything that I have forgotten about or that anyone can suggest?

Thanks for any info...Hagen
