Front struts are different 55mm types

[twosixtyzed]

1974 260z 2+2 bus is getting ready for RWC, got a few sticking points I was hoping someone might know?  Thanks in advance.

1) my mechanic mentioned today "you have two different front struts" and wants me to find one(s) with the "correct" brake line pipes, but we don't know which ones is the correct one?  RH has vertical hose mount pipe and looks correct.  Left is probably incorrect??  They are both 55mm struts.  The car was has lowered springs (I don't like the look, she looks like a dachshunds with the 14s) and I have the original springs.

I searched around the forum for hints and saw this, but wasn't convinced it is my answer.

2) He also said I am "missing a small directional shim for the calipers" I am not 100% sure what that is so I looked it up, I think it's the shim that adjusts the inboard/outboard position of the calipers the disc runs centrally between the pads? Is it this Part # 24-5450? It's current not available as far as my quick google found. I've read a correct-thickness hardened washer (~0.5–1 mm) might work?

LH is indeed incorrect. Can yo see evidence of it being modified?
Did you ask your RW inspector why does it matter? As long as no part of the hose assembly is touching anything, it's performing the same function.
There's no need to change the strut.

No. That's not correct. There is no such shim for that purpose - perhaps clarify with him what he means.
What 'I think' he's talking about the anti-rattle shim that goes between the brake pad & the caliper piston.
They do go missing, but are easy enough to obtain through someone like Stewart Wilkins at SW Motorsport.

RW Inspectors are a strange breed - they almost always focus on some obscure issue, while missing something else obvious...

Thanks man, really appreciate this!  I'll find out a bit more, not sure if it was modified or why there's a difference - probably someone's great idea at the time.
