I picked up a adjustable wheelbase wide front for an M/H. One of the knuckle/spindles was broken off. I've found an aftermarket spindle/knuckle that i think might work. Per the IH parts catalog the PN is 51699DF. Per this site and a few others the Aftermarket one is a replacement for 51699DE. I can't find that part on the CASE IH site. I'm thinking the DE may not be the correct p/n.
Here is a link to the aftermarket part.
