Not as good a rate as you can get at your CU, but okay. Any 'normal' financial institution doesn't have any idea what these cars are so you have to go with a specialist.
I have mine insured through Classic Car Insurance. Look under "Resources" on the JJ best website.
Good luck and look forward to having another Cobra in Texas!
