G'day

I've got a '98 Limited and I need to replace one driving/fog light because the original has become rusty. On the Limited the fitting for securing it is in the centre of the rear of the light and I can't find anything that will fit as OEM. I am restricted to finding something about 85mm or 2.5 ins deep

I don't want to buy a second hand light from a dismantler if I can something that fits. I've read all the threads, especially those that recommend PIAA 1500's, but unfortunately these all refer to XL's or XLT's not Limiteds.

Any ideas please?
