Hi Jonathan / all, I understand the Goose rack is from a Dauphine - very obscure model in the US, maybe same everywhere but France? The first series Renault 4 (1969) reportedly had the same rack but not later 4s, which used several different ones. The steering damper/coupling unit is Renault as well, there was a sqaure and round type on thier cars from this era. Inquiring at a classic Renault supplier like
