the mini and compac are similar size, mini is .3'' narrower and .5'' shorter
not sure what is different between the gmc/chevy in the passenger dash area but it would be similar to my install
the va system was one of the 1st things roughed in the cab as i wanted to weld in brackets and figure hose routing
then it went back into the box to outlive the warranty by 4 years before i first charged the freon
