Well, my mom might be headed to KS, but I don't think this will fit in the trunk of her Grand Prix.![]()



Take the springs off and keep them. Lay the seats down in her car. Done and sold!Well, my mom might be headed to KS, but I don't think this will fit in the trunk of her Grand Prix.![]()

The 3HD is part of the casting ID, and apparently denotes a certain offset of the pinion, as I understood it. It's from a '91 NBS K3500. I can measure the spring pads tomorrow.
It looks like 66" WMS-WMS. Spring pads look to be 47 1/4" on center. Those other pads are for the bumpstops, and yes, they're welded on.Chris, can you measure the WMS TO WMS please? What are the squares next to the spring bolts? Are they welded to the tube?

And thanks, sweetK30, for answering that while I was gone.![]()


Hey Robert - if you end up getting this axle I'll PayPal you $100 for that chopsaw. You could leave it with Chris (if he's willing to hold it) and I could get it from Palmdale pretty easy.
