Chin spoiler problems. Where did you get yours??

[turtle5353]

Hey guys. I tried fitting the chin spoiler on the 71 tonight and it's off by a mile. Almost 5" too wide total. I can't get it any closer than 1 1/2" on one side and 3 1/2" on other side. I'm wondering if they packaged the wrong one?? The instructions inside are for a 69/70 but the packaging says 71/73. The owner ordered it from CJ pony. I will contact them tomorrow and see what they have to say. The valance is factory original from the car so I know it's good.  It was made by California pony cars. Who have you guys used with success?

Hey how did you mount in underneath ? Cal pony makes a good spoiler, they usually fit well

On the 71-3 you need to drill all the holes, no factory spoiler holes in the valance.

The problem is you followed the instructions first, that paper is to be used when all else fails

Don, I just temporarily mounted it with small c clamps. No matter what way I moved it around it's not even close to the same shape as the valance. And it's 4-5" wider than the valance. I have it set where Q's video said to mount it. I'm waiting to hear back from CJ pony parts. I'm hoping it was just packaged wrong. What brand do you sell Don? This Is one of the items the owner had already purchased or I would ordered from you with all the other items.

I'm wondering if this not a simple case where the plastic has relaxed too much after molding. I can't see that the tool would made be that far off. If it were, then everybody who bought this brand would have sent them back to the retailer and the manufacturer would have, should have re worked the tool.

I'm thinking that as there are compound angles involved here, you may be able to gently heat the corners and slowly reshape it to fit, then cool it with water. Without seeing the actual part it's hard to say if that will work, but may be worth a try, or at least look at.

 The one I have on mine was on the car when I bought it. I am not 100% sure, but I believe it was from NPD, but I don't know the maker. I have had it off a couple of times and fit is not an issue.

Is it about 65 inches OD ?

I think when I box these up the box is 65 X 17

If it is close to that it would be right

What happens if you clamp the L & R ends in the upper corners where they belong

Kevin I have a new one still in the box from NPD that my mother inlaw got me for Christmas. I will pull it out tomorrow and see how it fits my valance.

Here are a couple of pictures of my spoiler showing the way it fits. Perhaps you are not getting it on the correct angle.

 

[mach71351c]

Kevin, That spoiler is a reject. It turns out my spoiler is a CPC from CJ pony parts. It fit very well with little persuasion to make fit.

 

[turtle5353]

Thanks for the verification Mike! Mine isn't even close to fitting like that!

 

[turtle5353]

Hey mike. Just out of curiosity, what do the instructions inside look like?? They for 71-73 or 69-70??

 

[mach71351c]

Same as yours terrible 6970 instructions.

 

[turtle5353]

Well guys I feel like an ass. I guess I was not patient enough when installing the spoiler. I set it out in the sun and got it to relax all day. Did some tweaking with my heat gun and was able to get it to conform to the valance.  Turned out ok. I guess I should of tried a little harder. It did take a good bit of heat. Luckily I didnt damage it.

Looks great. Can you tell was it a vacuum formed part or injection molded?

I have no idea??

 

[mach71351c]

Looks good Kevin! Glad it worked out.

 

[73429mach]

Looks really nice!

 

[Stanglover]

Well, there you go! A little persuasion goes a long way. Glad it worked out for you and it looks good for sure. I always thought these cars needed something along the bottom edge of the valance, they just don't look 'finished' without it.

As for how they are made, they are most likely "Rotation Molded" a method whereby the mold rotates forcing the semi-molten plastic outward into the desired shape with centrifugal force. If it were injection molded, there would be a smooth inner surface as well as ejector pin marks. If it were vacuum formed, the inner surface would show mold surface marks as well as very small vent marks every inch or so along the edges. As the inner surface is "raw", untouched by a mold surface, then this indicates it was 'rotation molded'. One piece Plastic Canoes are rotation molded as an example of something a bit larger.

Geoff.

Edit note: on further thought, there might also be the possibility the part was blow molded, but I somehow doubt it for practical reasons. It would be interesting to find out for sure, but my money is still on rotation molding.

I'm almost certain that they are blow molded and that my former mother in law provided all the hot air.

Nice result-down in Tennessee we don't set stuff out in the heat, it's all heat this time of year.
