Hum Ali I don't have a G-3 nose strut so cannot say...please give me a measurement from the trunion block to the top sizzers lug.
The scale strut attachments, with some triming, will fit the G-3Mains.
If you already have the rear doors operational you will have to change a couple hinge points...the hardware to do this is included in the kits.
Oh yea, the cloth nacelle covers fit all generations.
