I was reading in the Registry (pg 672) that the Halibrand Cobra II (427) wheels were all magnesium. For some reason I assumed that only mags were used on Full Comp 427's and maybe S/C's. No mention of aluminum except for the Kelsey-Hayes Sunbursts.
There you have it. Any self respecting CSX continuation owner (especially an aluminum car)
MUST have magnesium wheels! There's no two ways about it.
Step right up! Please form a line. No pushing or shoving, please.
