well I had to make a decision on trunk hinges the tension rods kept binding hinge plates were worn out so I bought set of fesler trunk billet hinges and do they work slick the shocks are hidden and clean install here's couple pictures and yes they do work on convertibles

Those are sharp   They will be sweet, when you paint them, the body colour  

Nice work  .....

you're right carl must paint them color of car

do they incorperate a spring to hold the trunk open i assume they do but i cant tell by the picture as well where did you order hem through.

ok they work on a shock on each side hidden nicely below the hinge on the inside tension rods are history I bought them from fesler
