... Forged drop spindles for a mustang II are 175 for the pair from Wilwood, Wilwood doesnt make any for a Mopar, but PST is the cheapest forged drop ones I could find, 499.....
Just an FYI, doesn't seem to be a standard for KPI on the M2 spindles. Everyone is a little different. Also, the bearings are way undersized for 3K plus cars being tracked.
