Did you try Summit?
 
I've never seen offset crank keys before. I have seen and used the offset camshaft keys though.
 
Isky 4* offset crank key . Just had a look, old catalog. They had them for various engines, Ford V8s & Chevs. Mopar not listed, maybe one of the above might fit?

I’ll try to check my stash today but I’m almost positive my keys have Chevy marked on them.
 
Just be aware that 4 degree offset for a chebby keyway does not mean same on sbm. I ran into this issue and had me scratching my head. You are better off with a 9 way timing set. JMO.

Hi yes i knowe it wold be better whid 9 way but the one i got is brand new,im gona time the cam and see where im at then order if I need to iv found a dealer here in sweden to so il be allright thanks
 
Also note that you will have to do some grinding to the key to make it fit. I used the 988G and it was too wide and too long.
I believe the others are the same.
 
I have an offset keyway on the duster on the crank. It's kind of a weird deal because the harmonic balancer still has to be and it's true position so it's actually a two-piece...
