Convert stock rear to 5-lug disc or swap for F-Body rear?

[jeromio]

I have 2 different rear-ends from Firebirds. One is an 87 and the other is a 97. Both are 5 lug disc limited-slip. In order to use them on my 66-C10, I will have to cut off all of the various f-body suspension mounts and weld on some perches and a new panhard mount.

Or I could convert the stock rear to 5 lug disc. Which would you recommend?

This is independent of ratios - really just the amount of work.
