We have not done a Dynacorn AD but did do their 69 Camaro. The usual tweaks were required when mating factory and reproduction parts but would rate less man hours of labor over one from the rust belt. Not cheap with the out the door price in the 45-50k range. Have a 54 3100 hood in the shop right now with a repo hood that was a bit pricey and has taken major tweaking for the hood to fender gap and a lot of trimming and fitting to get the hood latch panel to fit the hood. Hood was at least a half inch too wide at the rear to cowl so rear had to be sucked in (not equally on both sides) and brace modified. This is a show truck with near perfect gaps so for a normal street truck the fit would be OK out of the box.
