GTO IRS in c10 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have been thinking of what to do with the suspension on my truck and would like to float an idea. What do you think of using a GTO rear sub assembly in our trucks? A guy on e-bay said he has a bunch of these and at first glance it looks like it may be able to work with our trucks. While I know someone like Nate or Scotts could graft them in and make them work, the big question would be how hard would it be to do so and would it be worth it for someone like Nate to make an install kit?

The assembly has 3.46 with locker, disk brakes, 5x4.75 bolt pattern, and a backing plate to backing plate measurement of 58". The front mount holes are 48" apart and the rear mounting is in the center behind the dif. The driveshaft connects through a rubber bushing so something would have to be done to connect it to a standard U-joint. The GTO weighs ~3800Lbs and the assembly is designed for a 400HP LS2.

So the questions are:
Will it work without a massive re-engineering effort?
What ride heights could be done?
Would anyone be interested?
