I'm building a buggy and I have an '01 5.3 that I plan on using for power. I'm going to use a TH-400 and I have had a hard time trying to find the parts that I need to use this tranny with this engine. Bolting the tranny to the engine is not a problem, what I need to know is how to hook the engine to the TC. It is my understanding that I need to use a special flex plate and a spacer in order to do this and that the spacer is a GM part. Does anyone know what the part number is for this spacer? What about the flex plate, is this a GM part also?
Thanks,

Speedo
