To open the front (trunk), there was a pull-lever under the dash alongside my left knee. To open the back (decklid/engine cover/hood), I had to use a pinkie and hook into the grille to lift it.
Very high-quality assembly by previous owner. Top-notch.
For the rear opening, you might want to look behind your driver's seat, alongside the door jamb at about shoulder-level when seated. When I hacked up my body, there was a little copper tube there inside the fiberglass that ran to the decklid latch bracket (on the body, inside the decklid), although the P.O. never made it work.
The copper thingie for the decklid is distinctly different from the convertible top assembly holes. Those were steel on my car.
Congrats on the new ride!
