I have a pair of 2" hub centric spacers sitting on my shelf I had to modify to clear the G body spindle/rotor on my 2+2. The inside of the hub centric ring hit the rotor hat.
I put LS brakes on my spindle so I had to go with a 1.5" spacer to bring the wheel back in. If you want my 2" wide spacer let me know, the machining is for hub clearance and wont affect performance if you decide to go with blazer brakes which I think you picked the parts up for.
$150 spacers? I think my pair of 2" was like 30 bucks on ebay, unless you are going something specific.
Still totally jealous your finds. Makes me want to move down south, the frozen northern tundra doesnt have these deals
