By the looks of your No. 1 body crossmember, you'll most likely have rust holes in the bottoms of the cowl panels also (just inside the lower rear corners of the front guards, where the outer subframe legs bolt on). While you're at it, take a good look at the front subframe tie member (just to the front of and below the radiator), the lower subframe legs, and the sills. If you're brave, take a look inside the rear wheel arches, at the bottom front corner where all the sand and mud accumulate.
It may end up being a remove-everything-forward-of-the-firewall repair job.

Thanks for the insight mate. You really know your away around that kind of rust. I’ll be sure to check it all over and determine the extent of the rust which will be fun. Thankyou again
