Best fitting headers

You do you... not my time or money with the shop.

I've had discussions with management 15+ years ago before petronix bought them out. They never fixed it. Sent the rep pictures of a dozen 73-76 cars with D453's on them. Same wrong fitment on the site/catalog to this day.
Thank you, D455 going back and have D453 on their way. Is a mini starter needed for the install and if so what have you used? Thanks again.
