I have three of the '67-'72 C50's, one is actually a '67 V5500, the cab is long gone, but, it had a front axle swapped in. This axle is a 10 lug axle which makes me think it is the heavier duty axle, I am planning to swap the axle into my current C50 but, unless I need the drag link for the swap, I'd be glad to sell it. If it has any identifying marks please let me know and I'll check mine. Also my axle is manual steering although the truck I plan to install the axle in has ram type power steering.
