NEED TO Sell ASAP 65 Cuda/valiant fenders & 8 3/4 axle.

Don't need the fenders but might be interested in the axle. Is it 4 1/2" on the axle bolt pattern or the smaller 3 3/4"? Any idea what it came out of? My son is looking for one for a 69 A-body. I would go $200 depending on what it would cost to ship. Thanks.
