Need help! I'm building an Estes Saturn V. The escape tower has two ridges on either side of a jettison thruster. Does anyone have an idea of where the ridges are oriented in relation to the capsule? Can't tell on drawings. My Saturn 1B instructions orient the ribs with the umbilical connection on the capsule but the Saturn V illustration doesn't show a thruster oriented there (thruster not oriented there so ridges can't be). Any help would be appreciated. This is the old kit and not the re-issue.
