Pain in the clutch

[Daddsie]

Split two engine's and boxes today to make one good unit, trouble is although both are 1098 units the flywheels are different sizes, the clutches different sizes and of the coil spring type, whereas the new clutch that I purchased today from a motor factors is of the diaphram sort and will not fit in any way shape or form.

Is there a mod, or is there a diaphram sort that will fit or do I stick with the coilspring?
