I bought this Shelby spoiler for my Mustang '68 and I need to cut the trunk lid to got a similar result like the green one. I know that is a fiber glass trunk lid with the spoiler included. Somebody did it?

Good luck, I hope your a good welder, fabricator. If not dont even try. To pay someone to do this would not be cheap.

Your best bet is to get a fiberglass lid and sell your original to recoup some cost...its far easier to work fiberglass for what you are wanting to do. I have done a lot of metal work in the course of my restoration but I would hesitate at that task since you would need some way to roll the edge back under after the cut, and while there are tools for that, they are rather specialized and tend to be several hundred dollars on the low end. A bead roller with the correct dies might to the trick.

You have a fastbk spoiler there it looks.
Coupe trunk lid vs Fastback lid
This is why they sell it as one piece trunk lid +spoiler


Mustangs to Fear has a 68 Coupe rear spoiler. Note curves

If that is a fiberglass spoiler it is meant to be bonded on . Fiberglass and metal really do not mix well though ,they expand at different rates and will eventually crack . Your best bet is a full fiberglass trunk lid .

Maybe like you said the fiberglass version could be the best one, but if this company sell a spoiler, probably somebody posted a tutorial o something like this...

The alternative is to have your German welder/painter build a metal spoiler (replicating the fiberglass one you have) directly on your trunk lid, matching it with the end caps in place.

No dissimilar material issues and your car will be unique.

I knew I just saw this somewhere recently...

My Homemade GT/CS Steel Decklid

My GT/CS tribute I am building came with a new uninstalled fiberglass decklid and endcaps when I bought the unfinished project. I'm not impressed how most of these seem to fit and this was no exception, so I had a brand new steel decklid that fit great so I decided to build my own. As I am...
