AC pressure switch

I did an R134 conversion on my 87 740 GLE. Thanks mostly to the Brickboard all went well.
However I read that it is important to recalibrate the pressure cycling switch to cycle the compressor at 24 psi for the R134 as apposed to 30 psi R12 for maximum cooling.
The only two pressure devices I can locate are the relief valve on the compressor and the limit switch on the dryer. I can’t see where the switch on the dryer can be adjusted.
Is there a way to adjust that or must I replace the switch.
Thanks, Louis Smith
