A 1987 would have been built with r12. It should be retrofitted to R 134a.
If it is the original refrigerant, it's R-12 (which is not longer available). If it was converted, it has R-134A. You can tell by the type of service port (the fitting for replacing the refrigerant). The service port for R-12 has threads, R 134A does not.
A 1987 Chevy Blazer uses R12 refrigerant as shipped from the factory. Most have been converted to the more environmentally friendly R134a.

7-25-10 - - - Answering your question about the type of refrigerant in your car. Probably Dichlorodifluoromethane (R-12). Newer cars use a different type called 1,1,1,2-Tetrafluoroethane, R-134a. Automobiles started using r-134a in the early 1990's as a replacement for the more environmentally-harmful R12. Retrofit kits are available to convert the R-12 to R-134a. This option might be better for you because only a person with a CFC license can perform work on and purchase R-12. However, banning the sale of R-134a to unlicensed individuals is in effect in Wisconsin and might be soon on California. The newest will be a replacement fluorochemical refrigerant 2,3,3,3-Tetrafluoropropene, or HFO-1234yf as early as 2011. Good luck with your car. 1987 Nova - - - COOoooL
