2/3tg Cam sprockets interchangble with 18rg?

[Stoimy]

Does anyone know if the cam sprockets off a 2TG/3TG will fit on 18rg cams?

What about the upper timing chain guide in the head, are they compatible to the 18rg also?

My sprockets have mysteriously vanished from my engine that has been in storage for somtime, and the upper chain guide has also vanished too.

Any input would be appreciated.

top guide is the same and so is the long 1 going down from the exhaust cam and the 1 up agianst the top tensioner as well
on sprokets for the cams, provided you have the latest 18rg with fuel injection they will be the same as a 2tg ,but if early model you will be in the shit with the 3 bolt holes
