Worth it?

[K20-69-POS]

I currently have a 14 bolt waiting to bolt into my project, but there is one for sale that is right around an hour away that seems pretty good for $700 the pros & cons of each are listed below, Should I buy this axle and sell mine for some idiot on ebay or should I stick with what I have?

Axle I have:
Pros:
-Spring pads are there and I should be able to bolt them in the '69 K20 (right?)

-I already have it (no traveling)

Cons;
-I plan on converting to disc brakes which will take time and money

-I have no way of proving this but may have been mis-treated (drum is cracked and shock mount broken off.

Other axle
Pros:
-Already converted to disc brakes. (saves time, and then I won't have to buy stuff to convert)

-has a truss welded on
(http://diy4x.com/cart/index.php?rout...product_id=151)

- New bearings/ seals (not actually "just put in" they were put in 2 years ago, but axle was never used)

-Rotors are usable
Cons:
-$700 (already am $900 into mil-spec dana 60 and 14 bolt rear, so I would need to sell the rear I have now for a decent amount)

-surface rust (equal to or less than the one I already have so really dosent matter)

-1 hour away

-Spring pads are gone, set up for coil springs, so would have to cut those off and weld on spring pads & shock mounts (I have to weld shock mounts on the axle I have now too)



*Again I would try sell the one I have if I purchased this one, I would try to get $500-600 out of it,
WHAT WOULD YOU GUYS DO IF YOU WERE IN MY SITUATION?
