35 mph WOT power loss

The a/c does not work, never has. The ac clutch on the compressor works but the system is not charged. It needs charged, new hoses, a dryer and a new condenser... its a project for another day...

For what's its worth I deleted the a/c on my 86 D150. It was pretty straight forward and im only running one less belt. Didn't have to change bolts or anything.
