Thanks Fatmobile. ^5 (hi-five)
Looks like whoever/whenever did this work, did both sides at same time. Identical condition and appearance on all the boots. And the Truck has a million and 61 thousand miles (rolled over). So i know they are not the original boots, pretty much for sure.
The pass side had no puck/cap.
So that is why i'm thinking the driver side won't either.
Going for safer than sorrier, just to see.
After i had about 3 bolts out of the pass side - the tranny lube started dripping out the bolt holes. I started cussing.
Knew that wasn't a good sign.
One of the bolts had been stripped already inside the triple square.
They must have done it when tightening it back up.
Because it was the tightest of them all (#@%$&).
Prepped it, tapped bit in place solid (did that to all of them), hoped for the best, nothing doing with this one.
Tried every pair of vise grips in the shop, every allen head, star bits,
impact driver bits .....
Thought i had a good deal going when i hammered a box end 12mm wrench over it - but that didn't work out either.
Spent about 2 or maybe even 3 hours on that last bolt.
Including breaks for cussing, smoking, re-thinking, rummaging through everything i have to find something else to try, etc...
FINALLY - thought about trying to hammer/chisel the bolt strap down, with hopes it might give the intial movement to break the torque of the bolt - well it worked.
Thank God.
Half a turn with vise grips after that, and it came out by hand.
About 3-4 ounces of tranny lube came out into the catch pan by the time it was all over.
The new CV/Shaft assy came with new trip-square bolts.
But i might check for some suitable allen heads instead. lol
