Vintage Air ac install questions

[snappytravis]

I am getting ready to install my ac setup on my 69 camaro. I have seen many people run the hoses through bulkhead fitting below the pass fender bolt, and some run the hoses through heater blower hole with rubber gromets, what are the pros and cons of these from people that have ran them both ways, It looks good with them hidden under fender with gromets and less connections but the bulkhead looks like it would be easier if it needs to be worked on. thanks for the advice
