Thanks so much Gus. After some serious searching for some other bits I finally unearthed the wayward parts, last night, underneath the bead blast cabinet of all places

Feck knows how they go there!
With this project having stalled so many times for paying bikes, it has become impossible to work out which parts have been skipped cos they're fecked and which have just been buried.
