Spit Swing Springs

["Vincenti, Ross" <VINCENR@transamerica.com>]

Okay, okay.  Now I'm confused.  Andy Mace advises that the rear leaf swing 
spring on the later Spits is the same length as the earlier non-swing spring 
Spits, however the axles are longer (no dispute about that last part).

So am I to understand that I CAN bolt in a later swing spring with 
absolutely NO other modifications to my Mk I Spit?  If it is the same 
length, then why longer axles?  Thanks for the anticipated responses
