I need Input before I start!

[GMC69]

After 2 years, and now have access to my truck again( moved out of town), 69 GMC fleetside long box. I want to get it out of "storage" and get some work done to it. Before I start I wanted some input,

So this is what I have planned for the truck: install power steering and power brakes off of my donner truck ( approx an 83 pickup) also convert from drum to disc brake, change my staight six to a v-8 and of course lower it. Now since I have my donner truck should I swap the front suspension, ( would it then be easier to convert to disk brake, power steering and lower) or keep my current suspension and work with that.

I was thinking of just getting drop coils and drop shocks for the 4 corners since it is a coil suspension on it now and it's cheaper. But if I convert the front suspension then I would get drop spindles.

Any comments or help is greatly appreaciated, oh and one really important thing, does anyone know a place to get my parts in Canada, preffereably in Ontario, since duty costs and freight will kill me on a few things i have planned later.
