300tdi/TD5 Exhaust problems.

Hi all, just wondering if anyone can offer me some advise. I have a 94 defender 90 with a 300tdi engine but the chassis has been changed for a galv TD5 chassis with the fuel tank at the rear. I can't seem to find an off the shelf exhaust that would fit properly. I can't really afford a custom S/S one. Any ideas would be welcome.

Would they one for a 19j / 200tdi fit as this doesn't effect the tank area between the rear chassis rails

ESR4526 and ESR4527 should be mid pipe and tail pipe for a late 300tdi with a rear tank.
