Help me Id which turbo action valve body this is

the 35xxxxx case number is a change in the front servo....

I just read instructions for the 70 don’t need to do anything but the 35xxx need to plug the hole for accumulator. Unfortunately I done have the accumulator piston blocker or rear servo shim. Any ideas what diameter and length those need to be? Otherwise looks pretty straight forward. Just not sure if should go with lba or not.
