When  I go to mount my side pipes on the 72 I want to be sure I have all the pieces I need to do the job right. The covers I am using are the aftermarket covers that came from ecklers. Is there anything else that goes between the covers and the actual pipe, (I dont have anything for there) and will the covers get very hot or will they stay cool? Looking at the original factory set up there appears to be a piece between the pipes and cover. (saw this on corvette central originals for sale)  
I have the rubber bushings that go to hang the actual pipes to take the vibration away, but I dont have the brackets that I see being sold as part of the mounting kit. I know I can buy them for just under $20 bucks apiece. are they really needed and does anyone have any pics of how they mount and what they support.
Also I've read somewhere that a carriage bolt is used to mount the pipes and the head goes into a slot on the underside of the frame. Is this correct?  
Lastly does the cover mount using the same bolts that go thru the rocker panels once they are removed or do I need to find a different bolt?
Thanks for any help you can give me. Below are pics of what I currently have.

I have the OEM repro covers on my '81. There is a piece of fibreglass type material that is riveted to the cover. That is the heat barrier for the metal covers.

I bought the hardware kit (screws and nut plates) to mount the covers to the car. On the later C3's the rocker molding bolt pattern in different. I placed the cover up to the car and marked the bolt holes. Drilled them out, put the nut plates in then secured the covers to the car.

The rear braces are necessary to give a good support to the rear portion of the cover. I can try to get a pic emailed to you if you'd like. I'd post pics here but it's a PITA IMO. 

The mounting bolt and rubber bushing should slide into a slot in the frame. Later C3's don't have this slot. I had to use a drill and pneumatic mini saw to form a slot in my frame.

It's all a PITA to do but worth it in the end IMO.

If you click on my link below there are some pics of my side pipes. The pics with the catalytic converters you can just see the insulation barrier riveted to the covers.

Hey Sarge, Thanks for the reply. If you could send those pics to my email that would be great. Its rod7515@verizon.net. I am assuming that you believe the rear brackets are important enough to purchase to make a solid installation?
Again thanks

Yes the rear brackets are a must for a nice solid mounting point. There will be to much flex at the back without it.

Tomorrow after work when I have my cruddy duds on I'll go out int he garage and get some pics for ya.

Thanks sarge, Will look forward to seeing them. Appreciate your help with this.

Pics sent. Let me know if they came through ok. Hope they are a help. 

Darryl,
Pics came through. Thanks for your help. Hopefully I can send pics of the car with sidepipes in about 2 - 3 weeks!
Again Thanks
Rodney

I'll be looking forward to pics. Love sidepipes. I think every C3 vette should have been offered that option throughout the years. 

You do know ya got to trim the front fenders to get the covers on right ? I had to do it on my 71 .

I think that in an earlier stage of this cars life it had pipes on it before. It already has notches cut in it behind the front wheel. Im hoping that it will be at the correct positions. Theres no turning back now as I already have the headers sitting beside the car!
