What's everyone tried for UR Quattro track/tie rod replacements as the OE are NLA?

I'm looking for new ones for our Group B tribute rally build (https://www.audiforums.com/forum/cla...1/#post1507098) and wondering if anyone has any experience with the few solutions I have found or even better options. Our car is an 83 with a rear anti roll bar so rears are long and fronts are the same all through, right?






Current ones are shot:




Here's what I've found so far:

AKmotorsport.net in Poland has front and rear available at a reasonable price:

and CCC Motorsport in Germany have fronts:

Any experience or opinions?
