Isn't it just the car that is teched? Gilbertson is on the entry list, so I assume he had the car go thru tech last Friday. I remember the rule used to be u could switch drivers, but you would lose any qualifying passes made by the old driver (kind of like the NASCAR and open wheel rules where due to a driver change, the car is placed in the back of the field), so since no passes where ever made, Gilby could substitute Whit, basically without penalty...of course, this may just be a dead rumor. I guess we will find out Friday.
