I have a question regarding these spindles and spindle mounts for 58 - 59 truck. Aren't the brackets where the spindles attach to the frame different for the V8 as compared to the 6 cylinder mount? If you wanted to swap in a small block in place of the six and wanted to use the front mounts rather than the side mounts, are these brackets re-popped or is the only way to obtain them is to find a donor frame? Thanks in advance. Gary
