P3 XC70 - Fuel Tank Shield - Which part is right?

[y2kdad]

My passenger-side fuel tank shield got snagged on a metal road construction plate and bent it downwards. I tried to bend it back up but I'm afraid it's going to snag on something again. I asked the local Volvo dealer for the part and he told me it is Part# 30793512 which is a heat shield. I'm trying to figure out of this is really the part. I've seen other parts (just a plain old Fuel Tank shield, part # 31200365. This part is much cheaper but I don't want to order it if it's the wrong one.

I'm unable to attach a photograph of it, but I can email it if needed.

Thanks!
