304 to TH400 Spacer

Does anyone know if these are available at a parts store? I know for sure my truck does not have one. I've had problems with cracked flex plates and wonder if this could be the cause. I go thru at least one a year.

I am trying to understand what you need. Do you mean the plate that goes between the trany and block? If so I those. Other than that I have no idea what you need? Let me know. ;)

On an earlier post "360 to 304 swap", A spacer is mentioned that is in the end of the crank of a 304 with a TH400. I had not heard of this before. I know my 304/TH400 doesn't have one and wondered if this could be my flexplate problem.
