Don't know if this will work on Avantis, but on my 57 Tbird I had a thin wire connected in the engine compartment to the latch leading through the firewall rubber gasket and a small handle on the inside of the compartment out of the way and not visible...cheap insurance for what is a pain on those baby Tbirds...
Avanti, Avanti ll, Blake, Kelly. No LSC or convertible, thanks.
Must be in good condition and automatic
Ideally in Pacific NW area if possible, as I am in Port Angeles, WA
