W116 300sd alignment

[xaliscomex]

1979 300sd needs front alignment. Do I pay for all 4 wheel alignment or is my suspension only adjustable at front only. Please advise. 69.99 for front, 20 more for all four

Beware.
This sounds like a shop that is looking for money. It is very likely they don't know how to do full adjustments of caster, camber & toe. The reason I say this, the only " adjustment" for the rear is an eccentric bolt arrangement.

Just found out that only the front is adjustable.

Bad news, the alignment shop won't do the alignment due to the upper control arm bushings needing replacement first.

They showed me the movement while the car was on the alignment rack and pointed out the bushings. They explained to time that this is the cause for the wear on the inside of the tires.

I don't trust the new owner but his guys are the same brothers that have been working there for 30 years. The owner doesn't know jack about alignments so he assumed it was adjustable on all 4 wheels
