Here's one:
"If OV-102 is used, the cargo-lift weight capability must be
decreased by approximately 8,400 pounds. This weight difference is
attributed to an approximately 7,150-pound difference in inert
weight, 850 pounds of orbiter experiments, 300 pounds of additional
thermal protection system and 100 pounds to accommodate a fifth
cryogenic liquid oxygen and liquid hydrogen tank set for the power
reactant storage and distribution system."
