I have a 1990 B2600i truck. It has had an aftermarket A/C system since I bought it in 1993, and I'm now converting it to a factory system. I have the new compressor and mount and idler all mounted. and I bought some factory pipes and hoses, as well as some factory rubber mounting insulators (number UB39-61-481A). I also bought a new condenser.

My question is; Do your factory A/C systems mount the condenser with these rubber mounting insulators? It seems like they will screw into holes right where the condenser will mount, but I haven't taken that all apart yet to see.

My aftermarket system is/was so loud, I'm hoping the factory one will be quieter.

The factory condensor was mounted with the rubber mounts but i removed alot of those to get the condensor closer to the radiator fan for better airflow and lower high side pressure/compressor longevity. So you can use them or not but i would'nt.
