To be a bit more helpful, it seems that making unique arms just to fit a set of wheels would be impratical. Such a venture would have pretty limited applications, catering to a very small segment of hobbyists, thus making it less profitable or practical. It is much more practical to do what is currently being done, which is either creating late model wheel copies with correct backspacing (as several aftermarket wheel manufacturers do) or more commonly, purchase correct wheel spacers to correct for the large backspacing of stock late model wheels. This is much less expensive and much more practical than creating unique suspension arms.

The purpose of the fatman conversion is to adapt the strut suspension and larger late model brakes with 5 lug spindles. Personally I don't understand why anyone would want a strut suspension on their classic, there's better solutions for the cost. Don't know of anyone who wants 4 lugs and small brakes either. What DarkBuddha said.
agreed, I think the fatman stuff is a waste of time and money. The original style setup but with GW arms, good springs/shocks, heim jointed strut rods, and roller perches would outperform the strut setup any day, and for less money. Plus theres some killer brake setups that work with the stock spindles. I really can't comprehend why anyone would switch to struts.
As others have mentioned, Fatman's kit is really intended to convert a vintage Mustang to a completely new suspension design (Fox/SN95 strut based with rack&pinion steering), not just to fit late model wheels. It's a pricey and involved conversion, and again, as others have mentioned, there are less expensive options that can provide better performance per dollar. Don't get me wrong, there may be benefits to Fatman's conversion (including being able to use late model suspension components, wheels, brake upgrades, etc.). However, most will acknowledge that the Fox/SN95 suspension design is hardly ideal and has much room for improvement. So ask, why spend all that money for that conversion only to have to deal with more (though different) suspension correction issues? You could spend the same money on real significant performance components from GW, TCP, Maier, Cobra Automotive, Baer, SSBC, etc. and get more improvement for your money. Just a thought.
