Looks like there is a fair amount of slop in the bolt holes. The shoulder on the bolt measured 0.746" and the hole in the k-frame measured 0.893". That's more than an 1/8" slop. The silver area in the below picture is the washer showing through the hole in the k-frame.

My plan is to use the TTI crank CL measurements and see where I am at and then put the car on a set of jack stands and see if I can loosen the bolts and shift it around depending on the measurements I get.
