Well, it's time to take the sunroof out of my project
I would like the car to be both legal for NASA & SCCA, so I decided to go with the steel route. The SCCA rules state that the plug must be of the same material & thickness of the original roof. I was going to use 16 gauge steel, but I think this might be thinner than the original body panels (I heard a rumor that body panels are 22 gauge)

What gauge steel have you guys used?

 

16 gauge is thicker than 22

its the opposite way around. 16 ga is thicker then 22

So what is it? Then or Than, gauge or ga? Other than that, I for the life of me can't see what you two are saying differently here. I agree with one of you I think

 

Kaan is correct.

 

yeah, I think "than" is right too.

(hope I am not seeing things and there was more to that)

 

lol..sorry 'than'

16 gauge is thicker 'than' 22 gauge...

 

So what gauge are most peoples' sunroof plugs?

 

my english is the product of fairfax county public schools + spell check... my metal experience is 2.5 years after college in sheet metal fabrication.

 

why does the sunroof plug has to be the same material? I thought composite is legal?

26G for this one... but who knows if it is legal.

It is for HC, but for SCCA you need steel

 

Your best and probably least expensive method would be to find the same car in a junk yard and cut the roof off and then fasten this to the race car in the shape you want. If you try a flat sheet, it may not contour as well to the rest of the roof.

I believe if the car has a metal sunroof, you can leave it in as long as you 'adequately retain' it in the roof.

 

I used metal from a dented hood I had. It's the original red hood from my car, so it's the same colour too. I then used red vinyl to cover the "seam" and rivets. Cheap, safe and it looks pretty good.

Obviously, I took out the support frame from the hood, using just the sheet metal.
