Need an answer ASAP

Hello. My '64 R1 Daytona is down at the exhaust shop and I am unsure of what kind of chrome tips should be put on the new exhaust. There was some confusion, as I thought they were rolled from the factory -so I asked for rolled. But the shop made a mistake and installed slashed. So, I looked ad the original accessories catalog and it shows a pic of turn downs. Can someone please tell me what is acceptable and was available from the factory? This car is a low milage all original survivor and I'd really like to keep it as original as possible. I have an opportunity to have them changed and just want to make sure I don't blow it again. Many thanks in advance. -Will
