Hi Ian, No problem, we all make mistakes. Owning two LS6 cars myself I know what an unumbered 064 fan blade looks like with a 4 rivet square design and different blade shape. All good, no payment required.
Good evening, It appears that I have made an error in thinking that this would work for my LS6.
If you have another opportunity to sell 7 blade unit by all means but if I own it as I said "I will take it" than that will have been the least expensive mistake I have ever made in this hobby.
Thank you for your consideration.
