Heater Box Assembly Question

[daveh]

Hey guys,

Were the heater/AC boxes always put together with screws or did they use clips to hold them together in later boxes?  And if so does it matter which one I use in my 71 Challenger?  Thanks

Actually the early ones had clips, no one is going to ever look at your A/C box, use what you have....

Most used both clips and screws.
