I dont know many who hasnt replaced the upper shock mount because the oem setup is weak and fails with time. A easy adjustment if needed.

The as delivered calvert shocks are big diameter truck shocks where ones like the QA1-a are easily 1/3 less in diameter. Not sure what Dave is using.

To me the only real question is the driveshaft engagement but the way most of us measure for a new shaft is regularly much longer then needed at least if going to the rear.

Yes check everything but overall your not building the next shuttle your just building your car. Daves a smart guy and what hes trying to do isnt rocket science.

Andy, why did you have to make your own lower plates or did you make a copy of the whole calvert system? They are nice looking parts.
