Sorry, never thought someone tried that. The link doesn't go to any info, dead end.
If you have seen the front sump you would know why I assumed you were not being nice. There is no way to flip it around. I could see the mounting bolt holes to be symmetrical, but there would be no bolts in the bottom half of the bellhousing. And the sump would hit the bellhousing.
The fabrication necessary to do that would far outweigh finding the factory parts. If there was a need to push the pan further back, it would make more sense to use the factory rear and modify that. Then you would have the correct mounting for the bellhousing.
