Help ID these front spindles please

[SSLance]

Helping a neighbor correct a 1979 eBay Camaro...can't get the ride height he wants because tires will hit fenders.



Stock OEM upper and lower arms, but this aftermarket spindle with SSBC calipers.





It's a 245/45/17 tire on an 8" wheel with 4.5" backspace. Looks like the steering arm will keep from going much deeper backspace...



Here is the brake setup.





The car won't be raced or anything like that, strictly a street cruiser. It appears to me someone put this spindle on just so they could use these calipers and rotors, but the spindle pushes the wheel WAY out...

Trying to figure out the most reasonable cost\part option to get the tire to tuck into the fender instead of sticking out of it.

Thanks,
Lance
