Which year frames will fit a 66 Coupe? What modifications will be needed to install a later year frame?
 
Beleive it or not, the only exact bolt in frame for your 66 without doing any mods is a 66.

65 is similar but brake lines are routed differently, easy to fix by drilling new holes for brake line clips.

67 is similar, but would require removal of 67 emergency brake bracket and instalation of a 66 emergency brake bracket.

63-64 both have different front crosmembers, line routings and additional frame mounts

New frames are available and IMO are nice, the welds are modern mig and lack the drag marks of an arc welder, but for a driver car you really cant beat them. by the time you find a good frame, adapt to your year, have it cleaned and painted (and have to fix anything unseen at purchase like "its bent" terrible to find out when its time for a body drop.) probably around the same money.

You can take a later frame 68-72, change the body mounts, add emegency brake parts, change the last few feet of the frame, and modify the front frame horns, and make it work, but it can always be seen as an incorrect frame without many hours of labor to make it appear orig.

Iggy Castro just sent out a sale message with a couple of $1000 c3 frames listed - if you are of a mind to take up welding to save money.

I think the conversion would require the exchange of the last 4-5 feet of the frame - and that would give you back the visible vin number on the LR rail. To prevent future problems, I would erase the other vin stamp under the LH doorsill - or chop and swap the doorsill vin off the original frame.
