Kyle,
I have got to give you a ton of credit. Most people would have parted out that 310 long before you got this far. I really hope you can get it all back together and working great, if only to show that it CAN be done

!
I hope to have a sidewinder some day, but if the "unibody" side frame pieces are that far gone, I am just not willing to put in all the effort reviving them takes. It is going to get harder and harder to find these older grills in usable condition however. Hopefully your mods will ward off rust and decay for many years to come

. We will all be watching and pulling for you!!!!
