New guy with a question. - roscop - 11-29-2018

Hello all, I'm new to the forum,  but not to Mustang's. I just recently purchased a Mach 1, in fact it should be arriving tomorrow.  It is a true one owner, unrestored car, black on black, 351 4v, 4 speed, AC, tachometer, 126k miles. The owner saved almost all the original paperwork including purchase order, warranty card, temp plates, etc. Has anyone here installed the rear slats/louvers that only use the double sided tape? I would like to add them, but I don't want to drill into such an original car.


RE: New guy with a question. - 1969_Mach1 - 11-29-2018

That's a beautiful 1970 Mach 1.  It's looks like it's at least had a repaint somewhere in it's life.  I might be wrong, but that's what it looks like.

Sorry to say, you have to drill four holes in the roof above the rear glass and another four holes in the bottom panel below the rear glass to install the window slats.  Then rubber nutserts go into the holes.  The rear spoiler is the same.  You have to drill holes in the deck lid (trunk) but nutserts are not used for that.  I won't install the rear spoiler or window slats on my 1969 Mach 1 because I don't want to drill into the body.  The drilling part isn't bad compared to the future repair if you decide to remove them.  Or the rust potential is moisture gets through the holes.

If you decide to install them, National Parts Depot has beautiful OEM reproduction rear window slats and a rear spoiler for these cars.  Both the rear window slats and the rear spoiler that NPD sells are OEM reproductions that they (NPD) developed so I believe are only sold by them.

I see what looks like Elite Motor Cars reflecting in the roof of your car.  Is that another classic car dealer?

Thanks for the compliment, and yes it has had 1 repaint. CJ pony parts sell's some slats that are attached by double sided tape with some hardware.  I like it becomes you won't have to drill,  but I'm not sure of the quality or fitment,  I was hoping someone on the forum has experience with that type, and would share their opinion.  The car wa purchased through Elite Motor  Cars in Concord CA,  it was on consignment. https://www.cjponyparts.com/rear-window-louvers-aluminum-fastback-1969-1970/p/RL2/

The OEM and reproduction rear window slats that NPD sells look much better.  Here is a link to the complete kit NPD offers.  These are concourse approved.  Basically identical to the originals.

I like NPD better than CJ Pony parts for reproduction parts.  Just my preference.


RE: New guy with a question. - Mustangmike - 11-29-2018

Welcome to the site Roscop  I really like the car.  It sounds like it has all the options I like!  Do you happen to know what gears it has?  Do you also know if the car was originally optioned with rear louvers?

If it were my car, I would probably have a hard time drilling holes in the roof and lower panel so I am with you regarding the  non-evasive rear louver with the adhesive.  Like 69 Mach 1 mentioned it is the future repair that hurts if you ever decide to remove them.  It's almost like getting a tattoo its there permanently.   However, I do like the louvers at NPD that have the chrome hinges. It makes the car look period correct.

I noticed CJ Pony had no product reviews.  I would look around and find product reviews to make sure no one has had any bad experiences with the adhesive or fitment.

Keep us posted on this car and post more pictures when you can.

Mike

I definitely agree that the NPD slats look better,  the car fid not come with them,  but I love the look.  Maybe I could get the slats from NPD, but use the installation kit from CJ pony parts to avoid drilling. I'm not sure of the gear ratio yet, I'm waiting on the Marti report.  It might be in the warranty card,  maybe you,  or someone here could help me interpret it.


RE: New guy with a question. - 1969_Mach1 - 11-29-2018

You might be able to use the NPD slats and mount them differently.  Back in the early 1980's the previous owner of my older brothers Mach manages to attach hinges and latches to the stainless trim around the window.  It worked okay.  When my brother removed the slats he merely had to get new trim for the window.

The tag on the drivers door will have the code for the rear axle and trans.  The engine code is buried in the VIN.  In your case, "M" is the engine code.  The most common manual trans and rear axle combo for small blocks back then was a wide ratio 4sp. and 3.25:1 rear axle gears with an open differential.  You'll know for certain after you get the car.

Here's a link to the original ad, and one of the current one, and one to the original owner's story

I am correct in assuming your brother was only able to get one screw per latch into the trim?  I would not recommend doing it that nowadays if your car maintains its original molding.  The quality of aftermarket trim pieces is hit or miss. Nothing beats original.

Hey Roscop, Welcome to the forum. Very Nice Mach1 Wow. I can't help with the Louver issue sorry. Unless you want to sell it in the future, I'd install the factory correct parts. Even if I had to drill holes, as that is what was done to most of them, before they left the dealer. The fact yours didn't get them is surprising. All depends on what you're going to do with it. Still, Very Nice Mach1
