First question is if the 87 had A/C from the factory.

The reason I ask is that A/C and non-A/C trucks had different firewall openings. So if the 87 did NOT have A/C originally, you will have to modify the firewall to accept the A/C parts.

Not that this cant be done, just that you need to know it going in.
