I've checked the harwood catalog and they don't seem to make it. Maybe they'll do a one off make for me. I imagine it'll cost a bunch though.

i saw this place in the super chevy magazine www.thespeedcenter.net (http://www.thespeedcenter.net) they are made though cause there is a 67 in the photo ads section that has one on it,,good luck

Try Glastek they make a real quality piece. Also VFN and UsBody Source. You find their websites on Yahoo or some other search eng.
I would avoid Unlimited their quality is pretty hit and miss more miss than hit. I had an unlimited hood for awhile and this guy came up to me at the track and asked me if i made it!
Ive currently run the 4" Glastek on my 64 its a nice piece and i've had USbody Source on other vehicles they were nice.
Good Luck

usbody.com has 4" cowl I have the 2" on my 65. I used a bolt on with stock latch.
Have it sent to your painter to save on shipping charges.

We just got a Glastek 4 inch for our 65 and it is made nice. We had ordered from OPG and waited 8 weeks for a "back ordered 4 inch from Glastek", had our body shop call Glastek direct they built a hood and shipped it in just over two weeks.
