Buy a kit at Wal-Mart or auto parts store. Will have to be converted from R-12 to R-134
Your 1994 Chevy pickup won't shift gears fast enough when the ac is on because their is a problem with it.
Depending on what religion it converted too, you could ask it to convert back......
Remove it, and install a shorter belt.
From the same port you would charge the front ac this is under the hood on passenger side of vehicle. John
It should be 134A, look at the fittings, if there are threads on the outside it's R-12. If they look like air hose quick connects it' 134A
0.060
