the aftermarket trans case's after there cert. expires? What will wear out that renders them to be recertified? Mine has the liner inside it, and NHRA says every 5 years!!!!!! do you all do this with your stuff? Calif. is a long way from Mi. to ship the case, and no way I am sending it accross the Canada border, sorry Hutch, that will cost me too much to send it to you to I think...
