Welcome to the Board and welLdone on your purchase of the Golde one!.
Ok no Vinyl roof was offered in 1960 only on the 62 Landau Models.
As for your Rail i may have a spare in the back of my Garage so will check, but you will have to have this part shipped in from England mate IF I HAVE IT.
There is plenty of photos and help procedures for you to follow on this site that will take you on a step by step picture view to help you get that roof working correctly. ARE YOU TALKING ABOUT THE 3 FOOT LONG RAIL THAT HAS 4 SCREW HOLES.
Private joke now, HEY ALEX I GOT TO TALK TO THE NEW GOLDE OWNER BEFORE YOU..MIRACLE..LOL.
Thunderbirds of England,
