Need a harmonic balancer, please

Would anyone happen to have an extra harmonic balancer for a 78 280z, I broke mine trying to get the dang thing off. The only place I could find one is motorsportZ and they want a little too much and I cant afford it. I am willing to pay for it and shipping any price just not too expensive. I have paypal if anyone has a paypal account if not I can pay by money order or check. Please let me know, it is the only thing I need to get my engine back together. I just need the timing marks to be in the right spot, I am pretty sure 75-78 will work. Thanks, Shane
