I don't have a LeTour, but a Miyata Two Ten. I would check and make sure you have clearance under your brakes for the fenders.
I can tell you first hand that installing these fenders so they look correct and function is very time consuming. I had to measure, install and removed the rear fender twice and the front three times. And to be honest, I 'm thinking of removing it again because it is sitting a little high on the top of the front wheel.
It's involved but nothing looks quite as nice in my opinion.
