@azaustin, I have attached a picture of the two different styles of the under hood straps that we manufacture. There is actually two more as used on the C and E and 71 to 74 B-Body applications, but they are black nylon, so I did not picture them.
The "flat" style has been documented as for the 62 to 64 B-Body Max Wedge Applications. The style with the bump was used on the 63 to 66 A-Body and 66 to 70 B-Body applications from what we have been able to document. Both styles from the center of each push pin is 2 inches.
As for the A-Body applications, we have developed kits in the following classifications:
63-66 A-Body
67-69 A-Body
70-74 A-Body
Hope that this might help,
Richard
