Axle is in good condition and has a lot of it's original paint, I believe the rubber mountings will require replacement.
I purchased this many years ago for a project, didn't use it and it has been in dry strorage ever since.
Not sure which Sierra model this was originally from but I have been assured that these beams are all interchangeable even with the Cosworth 4x4 models, I cannot confirm this.
Pictures are of the actual item for sale.
