Scalextric TransAm Camaros

I just purchased the Todco TransAm Camaro and I was disappointed to find that the guide holder was one of the older types. I experienced a lot of problems trying to fit a Bnova adapter into the guide hole so that I could use a Slot.It CH-85 guide and, in the end, wound up reaming it out with the next larger drill bit and filing the sides of the Bnova guide, in order to get a good tight fit. I messaged Brian about it on another forum and he answered back that the Todco car is a relatively new release off an old chassis mold.
So, since I don't want to have to deal with the older type of guide holder again; and I need another TransAm Camaro for an upcoming race series, I wanted to ask: which of the Scalextric Camaros have the newer guide holder; like the one that comes on the blue Petersen Camaro? If I know ahead of time, then at least I should have an easier time with using a Slot.it guide via the Bnova adapter. Thanks.
