The Yugo Model 24 was purchased from FN in Belgium, along with the machines and tooling to make it, later used to make the Model 48. The FN Model 24 action is based on an early version of the Model 98, and is shorter than the "standard" German Mauser and Czech Model 24 (Vz-24).
That makes a difference when ordering some types of scope bases, bolts or bolt parts, magazine followers and floor plates, etc. It also makes it very difficult to convert the short action to a caliber like .30-'06. I am sure someone has done it, but there is no room to play with.
