2000 Excursion XLT, V10 with front and rear a/c.

I found the numbers here before but have searched again and can't find them again. Can someone help me out?

Looking for proper high/low pressure readings for just the front a/c on and with both front and rear a/c on.

I need to pull a vacuum and reload, but I think have a problem somewhere and need to know what the right pressures should be to help diagnose.

Thanks!
