I really like what you did you bounced it off here as far as opinions,
and I too dont like drilling holes in fine vintage steel but the tape idea is great, but yes if it fails it would be .........well embarrassing to see that thing flying off in to the air
,
I am in the middle of doing a resto and I just dont want to drill holes for the vynal top so that idea is nixed
and there is trim above the doors and I have new 1/4s and I dont want to drill those either so the tape idea might work for the trim on the top of the doors and 1/4s it is pretty light.
I am also wondering if taping the chin spilers would work the repro ones that are really light.
as far as drilling you deck lid its your car .why not give it your personal touch and go with it I think it looks awesome, and besides these new repro deck lids are really nice , so if someone down the road wants to change it back they can
