Epoxy for old plastic dashboard repair?

I have a '70 Chevelle that I, in a moment of haste, snapped off some of the tangs while pulling the dash to fix the heater core.

It is that brittle plastic that came in every 70s car - nothing seems to bond with it. The only successful repairs I've done involved melting pieces of ABS with a torch "welding" it. I am looking for the JB Weld of old E36 M3ty plastic so I can make it stronger around the area it failed by maybe weaving in some cheese cloth or even screen.

I'd use a soldering gun with a wide tip to melt it back together.

Super Glue? Neither JB weld nor real 2 part epoxy will bond. Possibly PVC Cement could work but Ive never tried. Bondo? just tossin stuff out there. Maybe make a Fiberglass mold, then a plug, then make brandy spankin new 70s Chevelle dahsboards out of fiberglass?

Baking soda and super glue mixed to a paste works on motorsickle plastic body work.

Gorilla glue?

I've repaired and reinforced a few plastic parts over the years by taking an appropriately-sized nail, clipping or grinding the head off, heating it red-hot, and either laying it across or inserting it into the pieces in question (as appropriate). Nails with little ridges (I think these are intended for paneling or some such) work best, as they have additional surface area, or you can scuff up the nail before heating it. Don't do this with galvanized or otherwise coated nails (at least not without adequate ventilation). Combined with the plastic welding techniques mentioned above, this will result in a fairly strong bond.

I've always been a fan of west system epoxies -- I would think that this should do the job for ya...

There is a special epoxy for plastic available at some hardware stores. Makde sure you clean the surfaces to be bonded with acetone or isopropanol and dry, If you can rough up the surfaces with corse sandpaper.

Oh and 3M super weather strip adhesive will stick to most anything and it is black and flexible.

the musclecar show on the powerblock this week had some bondo-ish product they used to fix cracks. seemed to work pretty well on the 70's car they were working on. it was the "blue collar buick interior and payoff" episode if you want to look it up there.
