In case you misunderstood, bolt #1 and # 2, in sequence, only had 1/4 turn before PB blaster was applied. I should have used it prior to trying to loosen the bolts. I got my manual right in front of me, so thank you for your concern.
Anyhow, like I said, a normal Craftsman 6 or 12 points 14mm didn't fit, that was why I tried the 15mm. I don't why but only that weird shape 12-points 14mm Craftsman, half the length of the deep socket,

would fit perfectly. Any way, I got all the bolts out and even got the sequence memorized. I'm happy...for now.
Thanks again for all your help.
