727 big block trans converter tighten/untighten tricks

Hello,
working on 68 dart
First time pulling out a 383 engine from the top with a 727 engine left in car. I searched thru all the posts but didn't see any tricks or methods on how to break free torque converter bolts by yourself as the engine spins. I suspect I could hold a socket on crank and break free the bolts on converter with a wrench just awkward by yourself on your back. Does anyone have a particular method/tool for this? Otherwise I will try wedging a pry bar or screw driver into the starter ring to hold it from spinning while cracking converting bolts free and for retightening them later.

My first mopar eng/trans separation. I had crawled under the car with a flywheel tool from JEGS pic below that I used on my last GM transmission removal and learned real quick that doesn't work on mopars!

Thanks
Greg
