Question Stock timing chain crank sprocket p/n NG!

Against my better judgement, I'm going to dig in and do a timing chain on my '87 T before the Nats. While I'm at it, I have a new set of radiator hoses, water pump, and a few other goodies. I'll also get the radiator rebuilt while the motor is down. There are also a set of RJC pullies to reward the car for putting up with the surgery.

So I went to order the chain and such. You have to order each piece separate from GM: chain, cam sprocket, crank sprocket, cam button (yes, I'm using the roller one), dampener, dampener spring.

So, Mr. Goodwrench is typing away and...turns out the crank sprocket is not available anymore. *sigh* Now, this is the same chain used on all the RWD V6 cars (4.1 Buicks, too) so there are a lot of them out there. How could they discontinue this?

So...what to do? I've got the rest of it coming. Use the existing crank sprocket? (Nearly 70k on it) Go with an aftermarket piece? (This is a car that is just in the high 11s and won't be going much faster, but I don't like surprises.) Use an aftermarket crank sprocket with this whole shebang?
