Well surgery went fine. Recovery is a little rough. Had to have upper jaw repositioned. Going to try and get back to work on my project next week. Anxious to get this rolling.

Worked on more of the finishing body work. Going to try and get it all wrapped up by next week. Been talking to a few different mold makers on prices and other details. Hope we can get this in production within a few months. I will keep you all posted.

That diffuser fits C6 bumpers, or the Carbon Creations C5 bumper that accepts it.

Glad to hear the recovery went well. I wonder if whichever company ends up making these will do a group buy for the first batch.

Can't be that much different
I used to be a bodyman but I'm not going to change the back cover.
I like the C5 cover.
Both ebay ads don't say anything about a different back cover.
If I can't trim it and/or do something to make it fit I'll return it.

FYRARMS is correct. From Extreme Dimensions' website:
"1997-2004 Chevrolet Corvette C5 Carbon Creations ZR Edition Rear Diffuser - 1 Piece
Note: zr rear diffuser requires the zr edition rear bumper"
Good luck with your "mod."

I can assure you that this will not fit the stock C5 rear bumper. You will need the Carbon Creations ZR edition rear bumper to make it work. I made mine to specifically fit the oem C5 bumper with absolutely no cutting or drilling. It is made from a base C6 diffuser that had to be cut and remolded to fit.

I'll wait and see when I get this diffuser as to what I can do.
Bodywork and fiberglass is no problem for me.
I may consider cutting the stock bumper cover.
That's one option
Or I can return this one then cut and remold a non carbon fiber one to fit.
Then carbon fiber it.
I've been wanting to do some of my own carbon fiber as per this thread
https://www.corvetteforum.com/forums...h-brplatz.html
This may be the part to do it to,
make lemonade out of my mistake.

The primary vendor is Extreme Dimensions (a supporting vendor), ....notice anything you've seen here before? They manufacture the parts referenced above. With the C5 ZR Edition Rear Bumper Cover in RED letters below you can choose any one of the 5 diffusers I posted links for below.
You can purchase direct through them or through Pete (Quik ZO6 / Corvette Creationz) who is one of their distributors.

There is a whole lot of difference between the C6 and C5 rear fascia. I bought two oem C6 diffusers to make up the one that I am working on. Plus I had to come up with a way to mate it to the C5 fascia. The diffuser had to be cut in 6 different places to get the proper fit. It had to be stretched 5" to fit the C5. Lots of epoxy was used to mold the contours of the C5 rear bumper. Also more material had to be added to achieve the shape needed. I have around $1200 invested so far making this piece and that is shopping for the best deals for parts and materials. Just want you to know what your looking at. I thought it couldn't be that much to it as well. More than what I was expecting.
and take my lumps 
The seller said if I refuse the UPS package they'll give me a full refund
We press mold SMC and composites
I know what steel tooling costs.
Hand lamination molds are cheap to make and you can turn them over 3 times a day.
Vacuum forming with fiberglass molds might be good for this for medium level production of maybe 6-10 parts a day.
You make a plug (the shape) finish it like bodywork to a shine, wax and PVA mold release then flange it add a gasket channel and make 2 halves one at a time, frame it, box it, backfill it with resin and roofing rocks.
Add in out ports.
Load the mold with dry fiberglass, pull a vacuum and pour the resin in
through a funnel.
This kind of low budget tooling can be made in a garage or a light industrial unit.
