Pressure plate problem

Hey Ive got same think going on with a new hays street strip clutch/ pressure plate& throw out bearing.Going into Reverse grinds like clutch is engaged. 1st gear cant engage. If you shut down engine can shift into any gear depress clutch restart engine acts fine try to shift into any gear at this point not happening. I think pressure plate is the problem,I have also adjusted the clutch good throw dont think I could depress the pressure plate any more, maxed out. maybe the clutch discs is to thick? please post any findings.Also had problem with a new hays fly wheel came so rough had to have it surfaced. Machine shop asked if hays finished it with a chain saw. Sucks when you spend good money for something and the company really does not care if theres a problem with the product. WHATS HAPPENED TO THE GOOD OL U.S.A.
