Cuda Capers: update
You've just got to love it when when something unexpected just "snaps in to place"! I'm guilty of using an old OE mud flap from my '89 4Runner daily driver to make a gasket for my Ramcharger steering column firewall bracket. Are our vehicles somehow tainted? I should think not! LOL! Good job John, and keep us updated.
I'd send those pics to Powermaster and ask them "what's up with this?". Spacers would just push the Alt. pulley out alignment I think.
