Thanks Jeff. Is it possible that my car could have come with the solid red stripe and not the Autolite/Date code?
Unfortunately batteries, fan belts, hoses and shocks were often the first things replaced back in the day so few examples remain and few period pictures were taken that show these details.
To the question. Here is what I think we have as evidence at this point
Your car
8R02S162374 Built June 5, 1968
Examples posted
Solid - 8R01C1673xx Built June 16, 1968
Solid - 8F01T20531x Scheduled build date June 11 0r 12, 1968
Some additional shots of that fine example. Notice that the hoses have not been replaced and the factory sealant is still on the hoes at the firewall in the upper picture
We do have other examples with the stripe and intergrated AUTOLITE and number but that was not the question
So trusting both of these examples (seen them both in person) IMHO the hoses were in the system around the same time as your car was built so I would say its possible though I would love to see more original examples. Bu then again I would like to see more of either original examples since both are difficult to find. Now that I think about it I didn't check any of the 68 Shelby examples. Maybe they will provide some additional data points to the discussion and possibly more solids.
