Thanks for the compliment on my 69 383-s. I had a 440+6 in it for most of the time I owned it. I rebuilt the original engine to sell it.
I have been restoring a few E-body Cuda grills for a Mopar buddy. The ABS plastic that is used on your grill is very easy to repair, and you can even make pieces if necessary. The secret is getting some ABS plastic and melting it in acetone. I had a small 1/3 cup or so mason jar that I cut up pieces from ABS plastic I bought on Ebay. Do about 1/2" deep of 1/2 dime sized pieces and pour the acetone over the top, about 1/4 inch above the plastic. Tightly cap the jar and let it melt down for a day or so. I call it goo glue. You can use that stuff to chemically weld your grill. You can even build it up and make sections that you don't have. The plastic can be sanded down to your liking. I use a little body filler for the final look. I like it thinner for welding and thicker if I had to build up a tab or something. ABS plastic can also be heated up with a heat gun and formed. I wish I would have know how easy it is to fix these grills and other ABS plastic pieces 20/30 years ago. I could have made a killing fixing all the broken stuff I have seen in the junk yards.
