Identifying V8 Spindles

[87_LX_5.0]

What is the best way to tell the difference between 4cyl and V8 spindles? Is there a part number stamped onto the parts or something in particular to look for?

i maybe wrong but the easy way is to measure from the spindle to where the brake calipers bolts on a v8 would be bigger. also if i remember the bearning on a v8 is bigger. so the bearning race would be bigger where the bearning goes on
