Yes on all of these apps for the air locker, including the one for the
D-70. And the one for the 70 can be adapted for the D-80 in some cases.
Dunno if they are doing one for the D-50 yet (another Ford not-so good
idea). And the one for the D-60 will also fit a D-61. Also--some Toy
pumpkins are covered. After all--ARB is from Oz.
