i removed my rear from both the 87 and 85 and found better heat but during the winter i cover the front ,found better heat covered and front only,then including rear,after replacing core because of low heat,note: if you overheat you can remove the cover quicker than re n re the stat.BTW put the settings on ac max in heat will fog windows but heats truck up quicker,then switch to defrost to clear
