recommedations for side saddle tank

[kxnomore]

Hi Everybody,
I pulled my factory side auxilliary tank yesterday to get it all cleaned out and working again, but the radiator shop said it was done for. It was a welded steel tank that was rusted to death on the inside.

Anyone know of any new side saddle tank replacement companies? I kind of like the idea of re-using the holes that were cut in the side of the bed for the filler tube, so if anyone has heard of a replacement tank that is just like the factory's that would be cool.

And if not, does the poly blazer tank that's in the LMC catalogue let you keep the spare tire? And how does the filler tube work with those?

Thanks in advance.
