Rear lower Front Wishbone/ Control Arms

[Hipcity]

Hi, would anyone know if the wishbones at the back of an A3 2010 8P 1.6 Petrol are interchangeable?  They appear to have different codes but look the same.  Wanted to check before ordering as see some advertising as left and right, while others are advertising as left only.   This is the rear lower front control arm / wishbone and not the one which the spring sits on.  Looking to replace both.

Many thanks in advance.

Hello Phil,

If not the spring pan itself, are you talking the straight link arm, or the curved one. 
Although I keep pushing this with no personal connection:- Have a look at Parts in Motion website. They are very precise in their descriptions , and I’ve got the impression the straight arm is handed - from not very good memory! 
If in doubt just give them a ring. I’ve used Febi brand to good avail. 
Please let us know how you get on Phil.

Regards,

Gareth.
