regarding weight of r134a

The 700/900 A/C system changed in 1992. That was the year they switched to a wider, thinner condenser and electric cooling fan. Everything up to '92 was R-12, '93 and later was OEM with R-134a. Normal ratio is R-134a at 80% weight of R-12...past 85% is almost guaranteed overcharge.
