What series U-JOINTS do we have on the rear shaft? I've read 1310, is this correct? I've found out that I have a 1330 series if there's such a thing in mine and its shot. I don't think the shop used the correct u-joint cause it never did feel right. I've only seen 1350 series on ebay. Looked like the 2nd gens use 1410? What ya think? BTW, where can I buy Spicer u-joints online? tia, Bill
