Cobraman,
You will NOT have any trouble putting in any T-5 in a CR's. The problem (Fairly minor problem.) comes with the T-56, the inner channels have to be narrowed and boxed.
Just my 2-cents worth, if you don't know Brent, (B2...) give him a shot at your estimate
MC, take a shot at the first opening (forward) on the T-5, I think you will like it, if you go to the second or even third you will be shifting with your arm almost bent backwards
let alone getting in the way of the E. Brake!
