Need Your input- Ignition Wires

OK- doing a restoration on a '68 383 motor. Things are coming together well until I come to installing the spark plug wires. I have all the "correct" clips in place (9) and date coded wires from Classic Ind. These things fit terrible, most of them are a little short, but #7, the longest of the set is about 8" too short. I admit I am very particular about ignition wire routing, but is this normal? What has been your experience with these repo sets? Should I be buying from someone else? Want this to be nice- what should I do? Help! Thanks.
