Not on here, but checking with some MB enthusiasts.......They are only known as Sway Bar Shackles and you can only get them genuine.
I was quoted by one supplier in Australia, 450 each, and another 370.00each.
I have since gone to the US and got them for 170.00US each plus $65.00 International fast post or $85.00 International Express.
The US advised me that they had to come from Germany...so a 10 day delay. I had placed order on 11th and on the 20th, they sent an email that the items had arrived from Germany, so now sent to me in Sydney South Coast...I should get them on Monday 24th.
They do not have 450SE in the US , only 450SEL....but they will fit either and also the 6.9.
All up $430.00 USD= AUD$540.00
I'd hate to find out they were cheaper here.....but if so, hopefully it would help someone else.
