Shocks recommendations

[ksshane]

Picked up a 71 last week and over the weekend I discovered that the rear shocks had been cut off at the top. Why someone would do this I have no idea, but they did.
I looked at the front shocks and at least they are attached but they all look like they havent been replaces since 1971.

I was planning on holding off to replace the shocks until I purchase my drop kit (drop spindles, lowered springs, and a flip kit), but now Im thinking its pretty unsafe to drive my truck in this condition.

If I go ahead and replace the shocks which shocks do you guys prefer?
