904 torque converter dont fit..?

Hi, If you read this thread there is a post that you will see where you can just buy an adapter spacer/ring spacer instead of changing transmissions and/or buying a new t/converter. I called Hughes and they built me a new convertor to the stall specs my engine builder wanted, cost $450. but it can be done with just the ring spacer
