They were added as an extra by Archie after Colin M knocked his firewall off!!!

Mine Ali,s and the boys dont have them and IMHO model does not require them. Belt and braces doubler is what they are.

Archie you need to sort this bit out if the builders are struggling with finding them as well as where they go

Original plan was drawn and printed before they were concieved.
