Power steering rack.....replacement options

[Jellomanpie]

G’day forum from Sydney 

(I posted hello in newbies to intro my project 306 and about Whilst in Covid-19 lockdown my son and I decided to take on a project car.......)

Thanks to internet and piggy power you tube We’ve done a fair bit ,but now run into a big thing (well, before we do timing belt and serpentine belt plus ancillaries)

Biggest query though is that I looked at steering rack today and noticed a worn gator on drivers side steering rack rod.   It’s full of grit and not much grease (shite steering doh!) in the steering rack. Probably not something I can refurb, though the rest looks ok......including links, ram and rods etc.

There’s not a lot of options for aftermarket Peugeot parts here and shipping is expensive.
Are there any alternative new aftermarket power steering racks that i could fit? 
Or other vehicle brands I could look at searching for?
Or could it be worth refurbishing it ourselves?

It seems like most folks have fun removing and refitting power steering rack........so tips appreciated there too!

Thanks for any help.
