Seems like the discussion has focused on 68 as Midlife kind of left it opened in the original post
Staying with 68 and looking at just some of the Marti reports (have 500+ if I wanted to go through all of them) here is what I found
Marti reports included Shelby's and non Shelby's
- Small blocks and big blocks with automatics have the tach and trip listed in the list of options
- Small blocks with manual trans have tach and trips listed in the options
- Big blocks with manual trans don't (at least in the samples even though we know that they received the tach/trip option on Shelby's) have it listed.
In window stickers of the ones I checked
- Tach & trip were not listed separately like they were in the Marti reports. And IMHO since they were included in the price they would not be - though, since the window stickers were often typed up by the dealerships some times they are found in the base description. But since some even include additional charges for other base offerings its difficult to figure out what the dealers were doing. Either they were padding the cost of the cars or something else but that discussion will get us way off thread
- Have a number of small block 4 speed non-Shelby with no mention of tach
