Stock TR8 (LP in EP) has hood louvers directly over the headers (one each side) and one at the base of the windshield.

I have a fiberglass hood but it does not have the louvers cut into it. I want to simply cut an equivalent area and nut and bolt on an off the shelf louver.

Legal? Would seem to be as the car had louvers (for venting hot air from the engine bay) stock.

The rule says that replacement hoods must have the same appearance as stock. Here's the rule:

Quote:
The hood, hatchback, deck lid and fenders can be replaced by components of an alternate material, provided their appearance remains stock.


Whether someone would get torqued about 1/4" one way, or less or more slats than stock, yeah I can see how some jerk would do that.

If you have the stock hood as a pattern, just do your best to imitate it. To me, that stands up in appeals court, as "same appearance" even if it isn't the same dimension to the 0.005 (which is not in any way required).

Don't add any hood bulges, or replace louvers with big holes, etc etc.

Just make it look the same.

I don't think I'd have a problem if you removed the section from the stock hood and put it on a fiberglass hood as long as it was in the same location as stock and it blended with the glass. No lowering or raising of that area. Be sure the glass good has adequate bracing so it doesn't flex or it will crack around the area.

As a matter of fact, the hood without the openings might be determined non compliant!

Thank you Jim, et. al. much appreciated.

The stock double bubble hoods are getting rare (the fiberglass one is identical) and I hate to cut the louvers from it. I've found some generic ones on line that are the same outer dimensions -- about 20" x 4". The slats aren't identical but they are close. I think I will go with those rather than cut a relatively precious stock hood......sound ok?

As long as it is close to same size and shape. Don't change overall size, area or number of openings. Find a rust bucket hood and gut it.
