I machine a lot of ABS at work and sometimes that requires glueing multiple pieces to get the thickness I need because they don't make the raw stock thicker than 4 inches. The best ABS cement I've found is made by Marsh Laboratories in Pittsburgh PA 412-271-3060. It's really inexpensive and is sold in 1 pint cans. Their stuff is a commercial version of Scott's mix, it's just ABS resin and Methylethyl Ketone.

I should have taken more pics.. but its on a Chevy Vega lol. Anyways I was frustrated with trying to make plastic 'shelves' for grills that I have that were broken.. a real PITA to shape, bond, etc. I'm into make model RC WWII aircraft bigtime, and familular with balsa wood. When finished properly, it harder the thermo/abs plastic, and the balsa has the added bonus of easly shaped to conform to whatever I need.
Thats what I did. Shaped fit a piece of balsa wood, then covered with resine ( that kind one uses with fiberglass mat). I then used a sponge brush to spread out the resine. Its almost self leveling, after it dries theres very minimal sanding to do, and one ends up with a very strong repair that after painted, looks 100% factory.
Pic below dosn't do it justice, but there it is in a nutshell so to speak.
So theres my little contribution to the MoPar community 
Ice, thanks for posting. That's a great idea/solution. I have a third grill that I could probably restore using that technique. Balsa really is great to work with and it makes total sense to use it this way.
I’m listening.

I bought a 70 cuda in the same condition. Who knows how long the header was bent. Pushed back about 1.5 inches. I pulled it apart and it did relax.

I machine and fabricate a lot of different plastics at work and have had good luck with an adhesive that will work with Polyethylene and Polypropylene. It's called Plexus and can be purchased here http://www.itwplexus.com/. They have a great technical staff on hand if you have any questions.

Scott,
I work for an OE autmotive supplier and was machining a prototype bass box (about 4 years ago) out of solid Polypropylene instead of the usual ABS and was looking for a way to bond the two halves. I called Plexus and they recommended their Methacrylate adhesive. I had my doubts but it really did the job and I have used it many times since then. The glue joint isn't pretty and would only be usefull on an area that is not visible because it really doesn't "melt" into the material the way MEK would. I don't really know how it works but it contains Methylmethacrylate and Methacrylate Acid.

Hmmmm..... the timing cover on my Mitsu eclipse is cracked and i bought a few plastic repair products BUT haven't made an attempt yet. After reading this...I'm wondering if one of the alternative methods might work better to actually fuse the plastic back together as it originally was. My eclipse has the same 2.0 engine as a DOHC avenger or Talon. Anyone know what the cover is made of and what will work best to repair it? I'm GUESSING its made of....polyethylene???

A lot of plastics parts are marked to show what type of plastic it is so look to see if there a symbol on there. If you have access to some MEK (methyl ethyl ketone) or methylene chloride you can rub some on the plastic with a rag. If the rag melts the plastic then you can use that solvent to repair the part. if it doesn't melt the part than it's probably polypropylene or polyethylene. If it's any type of poly you will need an adhesive called Plexus to make the repair. http://www.itwplexus.com/For abs repairs I'd recommend the ABS cement from Marsh Laboratories in Pittsburg Pa 412-271-3060. It's really inexpensive and is sold in 1 pint cans.
