The simple way is to use a straight wrench and a fish scale.
Measure the distance from the center of the bolt and to the point on the wrench (probably the closed end of it) and pull with the fish scale 90 degrees to the wrench. Easy to figure the pound-inches.

Hi  Bill,

Getting to second question first.  The only way I could  figure to get a 
torque wrench on those dampener bolts was to borrow  a  "Crows Feet" socket . 
The look like the end of a open end wrench  that has been cut off with a 
standard size hole punched for a socket  wrench.  You hook your torque wrench 
on the end of one the proper  size and it will slide in with sufficient 
clearance to get on the dampener  bolt.  A "Crows Feet" socket/wrench looks 
like  this:



Bill, 
 
If you are going to use the crows foot attachment, remember that you have  to 
calculate the actual torque provided by the indicated torque on  the  wrench. 
There is a formula for that. Depending on what angle your torque wrench  is 
to the actual nut/bolt, your delivered torque will be different.

Hi Bill,

It's been a while since I installed mine so I may be remembering this
incorrectly.  I think I snugged the bolts up, then rotated the flywheel
until each bolt was accessible thru the starter hole.  I probably
needed an extension on the torque wrench, but you don't have to
recalibrate it.
