in board out board tow links

can some one explain what i need…i want to refresh all tow links. i have alloy rear uprights. in board out board rear tow links

do i need a pair of in and a pair of out?

Yep.

Not sure about the Exige, but the Elise has several variants and a dealer will need a chassis number to confirm what is correct for your car.

Some were LH thread, some RH, and they also changed with ally / steel hub carriers. Both ends of the toe-link were changed

great. ok so where is the chassi number?
is it o/s rear wheel arch area?

Front n/s just ahead of windscreen when front hatch is lifted (at least it was when I last looked at mine)

And yes, OSR wheel arch, stamped on the chassis not on a sticker.
