Hi Sooner!
I have a '37 and I opted for a Fatman IFS (not a Mustang II). I wouldn't readily recommend it unless you've done them before or have a good fitter to assist. Like Hotrod Lincoln was saying, there is a lot of geometry involved and the documentation that comes with them can be somewhat sparse at times.
It took my brother and I two full days to get everything fitted and tacked in (you do NOT want to be cutting components out because you discovered an error in your plan!). I am very pleased with the looks and performance now that it's done.
Best of luck on your project!
