Even though the fiberglass is almost 4 times the plastic, my guy said go for the fiberglass.

My body shop followed the info here on mounting and the trunk does stay open without having to change the rods....interesting.

I'm in a pickle now... The alloy spoiler which I have doesn't have the indents for the pedestals like the fibreglass ones have. The pedestals I have were designed for indents. I've decided to get the grinder onto the pedestals since my spoiler isn't factory anyway... Live and learn.

I have a new aftermarket spoiler that I wish to mount on my 1971 Mustang Coupe, and I need to know the correct measurement from the top of the deck lid to the first mounting holes. I haven't been able to find these anywhere so far for the coupe. Anyone have any info? Thanks

The spoiler was not a factory item for the coupe
You will have to mock it up and put it where you like it.
You may need to make some longer studs to get through the inner trunk lid bracing

I don't think there was ever a special package for the mustang that included the rear spoiler. I attached pics of my original 73 that I ordered new. I do not have a good side shot to see where it is located to the edge of the trunk. The spoiler was a $29.12 option. I think the best deal of all the options was the black out or argent hood that included the hood locks for $18.00. You could not get just the black out or just the locks they came together. So if you see a hood with the black out or argent and no hood locks you will know it did not come with it.
The Mach 1 package included Trim Rings W/Hub Caps, Dual Racing Mirrors, Competition Suspension, Color-Keyed Carpeting and All-Vinyl Bucket Seats. Anything else was a cost add on.
I could get some dimensions tomorrow if you still want another known original factory install.
I see cars every day on eBay with the spoiler backwards and it is usually the high dollar flipper companies that just make them shine and sell them not restore them.
I would not put it past Ford getting one on backwards. They put my horn button on upside down was delivered that way.

(09-25-2011, 06:33 PM)Tnfastbk i went by the instructions that are on your page here and i measured it out and i went to do a test fit just too make sure they would be correct.and too my surprise the measurements were off by almost 2" glad i checked before drilling so now i am completely confused.this is a mach-1 spoiler did earlier years  have wider spoilers? Wrote: Well I found out the hard way last night that my car did not come from the factory with a rear spoiler and whoever installed it had no clue. It was installed backwards and flush with the end of the deck lid. When we attempted to just reverse it. it over hung the trunk by half the spoiler. So the deck lid id off to be welded up, re-drilled and repainted. Anyone have proper dimensions on the correct install.

****found some good info***** but want to verify it

Rear Spoiler

The rear spoiler was a factory option available on the Mach 1, Boss 351 and Sports roof. A low-gloss textured black paint was used on it from the factory. The diagram below shows the spoiler installation.

By the way, if you are adding a rear spoiler to your to a non spoiler decklid, you will need to change the torsion rods, otherwise, the extra weight of the spoiler will keep your decklid from staying propped open when the trunk is open.
There are two different torsion rods (aka springs) for the Mustang SportsRoof. The ones without spoiler are (D1ZZ-6344890-A and D1ZZ-6344891-A). The for use with a spoiler are (D1ZZ-66344890-B and D1ZZ-6344891-B).

Rear Spoiler Installation Location

If you want to install a rear spoiler on your 71 Mustang decklid, below are measurements taken on a decklid with a factory spoiler installation. Measurements of the location of the factory holes are shown in the photo at left and center left. The holes are centered 6 1/4" inboard of the decklid side edge on both sides. The fore & aft dimensions are as shown below and apply to mounting pedestals on both sides.

A note about the Correct Front/Rear Edge Orientation of the Spoiler

Some 71 - 73 Mustang owners have no idea that they have their spoilers installed backwards. As shown in the diagram above, the spoiler leading (front) edge is the thicker side while the trailing (rear edge) should be the thinner portion of the spoiler. When the spoiler is on correctly, the trimmed off edge (noted by red line in photo below left) will be at the rear. Check yours out!

There is a difference in the stud distance between 69/70 and 71/73 spoilers. You may have a 69/ 70 spoiler Off the top of my head it is around 33 1/4 VS 35 1/2

Anyone know where to find the torsion rods for the spoilered trunk lid?

- D1ZZ-66344890-B
- D1ZZ-6344891-B

Getting guillotined by the trunk lid is getting old Smile

There were several posts about this a couple of months ago. You should be able to find the thread by searching the forum for torsion rod.
