I have a 2003 Mach 1 and am deliberating over whether to get a roush short throw shifter or an MGW. Please give as much feed back on this subject as possible.
Best advice is to try to find someone with a MGW so you can try it out. Personally I like the MRT short shifter offered by Scott Hoag once the project manager for the Bullitt and the Mach 1. http://mustangracing.mrt-direct.com/shifters.php
I have it in my Roush I swapped the long armed JR shifter for a Steeda smaller one... and have been happy ever since.
I have the longer arm short throw shifter, and I like the quickness. It is less travel than even in the Shelby. The throws are crisp and quick.
I have a 2003 380R and just changed from the Roush short throw that was in there (Manufactured by Steeda) to the new HURST short throw and I think it is really great! shorter throw, postive feel. love it.
I have a new Roush short throw shifter in a box for my 06. I'm going to install it this weekend. I'll let you know what I think
