Dougs 67 Notch build

Thanks! I started with a 73 8 1/4 A-body rear axle assembly then I added 15" X 8" custom backspace wheels with 4 1/8" backspace. Then
I put 275-60-15 tires on the car. I mocked everything up on CAD to make sure it would all fit.
I have a set of 275/60r15"s that I was wondering if they'd fit my 67 cuda. Also curious about you experience,likes, dislikes about the gearvendors unit. I was thinking about on myself. Any vibration from the shortened driveline. Again,Great build post.
