EA82 crank pulley modifications (timing marks)?

[wagonist]

So a mate's mum crashed her spider manifold EA82T Vortex (XT).

 

I've put the engine into my wagon, but got some problems because the XT didn't have aircon. This means it also has the wrong alternator. And impossible to get the correct ones where I am.

I'm also adding a water-air intercooler from a 1st Gen Legacy, so the timing marks on the flywheel are impossible to see.

 

Because of wrong accessories, I've changed all the pulleys over to V belt, but this means I've lost the timing marks on the crank pulley. I will definitely need these as my mate made the engine previously run off a Series 1 "Black" ECU and changed the distributor. Mine's a Series 2, so I need to put the proper distributor back in.

 

Trying to figure how to accurately put them onto the carb pulley, along with drilling a locating dowel hole (which I will do first).

 

any help appreciated
