New age and classic front ARB
 

Guys I have a Perrinn Front 22mm adjustable ARB part number PSP-SUS-100 which is listed for the 02-07 WRX.

I have this for sale on SIDC but if it will fit my 93 WRX RA I would rather keep hold of it. Does anyone know if there is any difference between the classic and new age front ARB's and has anyone tried to fit a new age one to a classic. I am pretty sure the rear ARB's are the same but the front I don't know about.
Any help would be appreciated as I would rather hold on to it.
cheers
