Today I was fighting the two upper bolts on my bellhousing. After going and buying a two foot extension and some wobblers I spotted the Craftsman ratcheting box end wrench in my tool bag. I supported the motor, removed the two motor mount bolts and let it down to rest a few inches lower. The thin 3/8 twelve point of the box end not only fit the bolt, I was able to get it from the topside. 10 minutes and it was done. I've fought this battle several times, once even cutting through a junk block with a cutoff wheel to get em loose. The wrench I used was the flat laminated style held together with rivets. I hope this helps some fellow jeepers with the bolts we have nicknamed the G - d@mt bolts. Happy wrenching...:laugh3:
