Difference between s-2000 & f-2000?

[JETRep]

I've got a '96 FIII with a bad bulkhead so I'm looking for another sled to put the engine in. *I have come across a '94 Mach Z which I believe is F-2000 and I believe the Formula is S-2000. *Does anybody know if there are any differences between these sleds? *Any information I might need to know about doing this engine swap or any other engine swap would be appreciated as well.

JETRep: The 94 Z and the 96 FIII are both F-2000 chassis. Dino

those chassis are twins you are referring to.
