Air Shocks

Hi all, didnt want to start a new thread on air shocks. I'm thinking about a set of Hi-Jackers for the '70 Dart (Ive run them on my Caprice for 20+ years with no problems). Just curious where anyone who has them puts the fill valve, Id like to avoid drilling holes in the body/chassis if possible. The Dart is just a cruiser, no track days, just want to raise the stance a little for that old school rake.

Any suggestions? Thanks =)
