In attempting to mate up my 360 flex wheel to the B&M torque converter I discovered that the flex wheel holes are 1/2"wider measuring from center to ring gear. I ordered a B&M converter for a Th 400 and now I discovered that something is off.

Does anyone have any Ideas? My new Bulltear flex wheel is identical to the old one that I replaced so I know that the flex wheel is not off. The flex wheel was mated to the trans when I got it.

What do I need to use for a converter?
