I read it this way as well.The way I read this was that the CFTP cars will have the can installed already. If you have a base, you can buy it and install. If you have a GT or a GT350, you can use this, but only if you have those covers. So a GT500, base or CFTP, is good to go.
Something I just thought of......If all you need is the covers to make this work for the GT and GT350, is the hole already there and just plugged ?
Could you remove the cover, take the plug out, and create a hole through the EXISTING covers to make this work ? Hmmm.........
It’s actually surprisingly not that expensive I’m seeing 250 for the pair with all gaskets and fasteners.
The price also includes shipping. You will need to shop for a discount coupon to see if you might further reduce your spend. It took me over a half hour to finally get one to work. You have to copy the coupon code
