69 c10

[CRMW]

A friend of mine is offering me his 69 C10 at a pretty attractive price. He had had the body restored a decade or so ago and its holding up well. I think i'm going to pull the trigger on it but have some questions:

- There is no fan clutch on the truck but there looks to be room to install one. Any reason not to do it?
- The truck has drum brakes on the front, is the cheapest way to convert them to disk using a 73 and up front end? I'd also like hydroboost.
- Is their any reason to convert to 5 lug other than using the 73 and up front end?
- I'd prefer a lsd rear diff, do i have to stay with the same body style or will a newer diff fit? I have an 09 1500wt that is going to go for parts.
- I'd like to upgrade to power steering as well

I've been searching the site and coming up with lots of ideas but it seems that i get close but don't quite get an answer to my questions.

Thanks
