Good to see Sabrina going to a good caring home.
Going back a very long way Sabrinas photos by Kharn amongst others got me interested in RD 's.
As for repairs I have just found someone in the UK selling large and small tubes of Sil Poxy glue on Ebay.

( dated 5 May 2012 so will not be there forever)
Lot cheaper than from the States , hope that helps.
And if I remember correctly if stored in the fridge or freezer it will last longer once opened.
Good luck with the repairs.
