Bellhousing question

[kevins2]

One of the modifications needed for an ERA car is to cut the flange off the bottom of the bellhousing so that it doesn't extend below the chassis. I'm using a Quicktime RM6056SFI. To cut it off straight, I want to confirm at what points I can take some measurements. Just to "eyeball" it, I mounted the bellhousing on the engine and used a level to first determine that the engine is sitting perfectly level (checked level in 3 different places and all the same results). Then, I threaded the transmission mounting bolts in a bit and set the level across the bolts, expecting to see the same level reading. I discovered that the rear plate of the bellhousing (where the transmission mounts) is not in perfect alignment with the bellhousing - one side is about 1/8 lower than the other. This isn't precision measuring - just using a level, but it is accurate enough to see it isn't perfectly aligned. I measured as closely as possible using both the top and bottom transmission mounting holes with the same results. So, the transmission mounting plate isn't welded perfectly on the bellhousing. Anyone ever encountered this? This would mean that the transmission would be "tweaked" to one side about 1/8 inch. I'm not an expert so am seeking advice. This raises a red flag for me.

Thanks for any help.
