I stopped by the local dealer and did some measuring. The height of both seem to be very similar. I was surprised that the width is narrower on the Titan. I don't see how the Titan with its straight forward line will fit the curve of the Fronty. Some kind of filler would have to be made.
Just my observation. Was going to buy a set of Titan mirrors I saw on Craigs L. for $50 but after this comparison didn't think it would be a wise purchase.
