What a great looking car! That's probably the nicest 68 Runner I've ever seen. You asked for opinions so here is mine, I would not do anything more to it that would remove it from stock. I might tweak it a bit to make it faster but I wouldn't cut or weld anything else on it. 10.90 for a stock looking ride like that is a fun car anyway.
I loved project six pack the way it was, when they redid that car they did a beautiful job on it but I sure don't like it as much as I did before.
