Sounds like the holes in the flexplate are off, check that?

I had the same issue. Before installing the 904 in my Challenger, I bench checked and marked the flexplate and converter to make sure the bolts would line up. Everything lined up perfect and bolted together. Once I bolted the flexplate to the crank and installed the transmission, the one odd bolt was extremely hard to get started. I think the process of torqueing the flexplate distorts it enough that the bolts are all hard to install.

I would normally agree but Brand "X" converter came out and Brand "Y" will not bolt up. Just a guess Brand "Y" might be the problem. But it will be installed.

I don't know squat about Mopars but I ran into a FFFord once where the snout on the converter was just a tad too long for the back of the crank. It was just enough that you could bolt up the converter with no (noticeable) problem but it wasn't happy.

A little toy airplane technology and all is good. Thanks everyone for the comebacks and text. Toy Airplane Technology is a Dremel Tool or 5 Minute Epoxy.

Still to do: change oil and filter, install drive shaft, install passenger's seat, check logging graph, top off trans fluid, hook up auto shift, and test drive.

I did get to see all of the NASCAR race

Spoke with Brand "Y" converter maker and said they would gladly check it over and report. I expected nothing less from a quality company.
