    I wouldn't go past 70 , we got mixed up on Autozones site , and snapped a bolt on Allans motor using diesel specs , then after it was out , they went to 65 /forums/images/graemlins/k5.gif /forums/images/graemlins/k5.gif

    Let me tell ya what. That was a really crappy thing to happen. Took us quite a while to get the broken piece out.
