Rebel xt focusing screen made to show 3 to 4 crop lines- how?

[markfields]

I have the Rebel XT. I prefer a 3 to 4 proportion image, and of course being a "35"MM frame camera, it is

2 to 3 proportion. the higher end Eos 5d has a removeable focusing screen- in theory one could have it

marked with crop indicators for 3/4. The Xt does nor have a removeable screen. also it does not have

cropping in camera lines like the Nikon D80.

 

Does anyone know if there is a service where I can have the screen replaced or the one taken out and

marked with cropping lines so i can see 3 to 4 ration instead of trying to "think" the ends being cropped

off when I frame. I know the Olympus Digital slrs are four thirds cameras, thus the images are the

proportion I like- 3 to 4 but their newest camera is not going to be released in the US.

 

Any ideas are welcomed.
