87’ Engine Retrofit 86’ Truck Issues?

[Just call me Sean]

I would pull the brackets from an early '90s truck or van. My '93 truck has the short a/c compressor (same yours would have but with a serpentine pulley) on the passenger side, my '92 van has the next generation compressor on the drivers side. I have seen either on both, and passenger cars have other options. Brackets from passenger cars are more likely to have a place for a smog pump.
