Liner dumper steering rack bearings

[seraphim]

Gentlemen:- I've signed up for this forum in the hope that someone can help. At the Apedale Valley Light Railway, we have a Liner dumper, which is an invaluable piece of kit. Unfortunately, the steering rack bearings have been condemned; having stripped the unit down, this was completely right! Noting the debate in 2010, was a conclusion reached regarding replacement bearings?

In advance, thank you.
