if you are running an auto box you may need to make up 2 lift blocks and possibly a new xmember... but if you have it all in there atm, i cant see any issues..
i have also done what toonga mentioned in above post re castor plate and strut brackets (from memory, i used a hacksaw to cut a slice in the strut brake line holders, and used pliers to fold it back to slide out the lines, and i hacked off the castor plate handbrake tabs becasue i had alignment issues with the lift kit with them on)
as for the ej gear in the L body, i cant see any issues with the standard L lift blocks as they both run the 3 bolt strut tops. i had used outback struts and L strut lift with no worrys.
should be all bolt on... mine pretty much was.
here is my thread from a while ago showing the tabs on the castor plates i was trying to describe..
