To actually torque them to specs, you'll need a deep well 1-1/2" socket (if the bolts are 1") and a torque multiplier or one heluva big torque wrench. I actually bought a torque multiplier and the deep well socket to allow use of my 1/2" torque wrench with 3/4" adapters to fit the socket and torque multiplier. It cost me about $175 for the tools.
If I had it to do over again, I'd let the yard do it, although I don't think they had the tools anyway.
They really needed it. They were just beyond hand tight and the C&C smile required yearly patching. Since torquing to specs, the smile has not reappeared.
Check around and you can probably rent a +size torque ratchet and sockets. I got them at my local Ace hardware rental.
The info for all older C&C models is on the CNCphotoalmum.com The torque fl/lbs is listed by bolt/stud size.
