I have two after market sets of the scoop inserts. 1 is the thin fiberglass type. The other set is what the parts place sells, big bulky and thick and heavy. Both types need lots and lots of work to make them look anything close to right. $100 set.
Or I make my own that are a perfect shape and fit in an orig. 69 T/A hood ready to sand and paint. I do not know how well they fit in the after market steel hoods, but I know they would be alot better than the two other types out there. $500 set.
