Believe XC us the pick code of an original 7040268, have one of those as well.
Pricing on nice original 7040273's is way up there, know of several on here that have nice originals for sale.

So from what I have found even though the build sheet on this car has XC in the carb slot which refers to a 7040268 XC. (automatic). But actually installed a 7040273 WC being a 4 speed. Something about RPO? Anyone have knowledge on this?
