Need a timing gear & pully

I posted in a thread a little while back that i finnaly got my engine rebuilt and i was having trouble getting the timing gear back onto the crankshaft. well, i found out that i did get the wrong crankshaft, i talked to the autostore, and they said that there were to different sizes that they made for a 1991 crx SI(D16a6) which is the engine i am building. my question is that will it make a difference if i go ahead and use the crankshaft, and just find a gear and pully, if i can, Where can i go about finding a gear and pully, cause none of the auto parts stores carry them.
Thanks in advance for any info.

I've got two crankshaft pulleys. One was a stock spare that came with my car that's dimpled all on one end for some reason. The other one is from a 90 d16a6 I used as a replacement engine (I'm still using the Unorthodox crank pulley). I really don't know if it's what you need. The stock one is in good shape and I could let it go for $25 + shipping if you want it.

If it is off of a 90, then i doubt it is the right size, cause they switched the size in 91, actually from what they told me the use both sizes in 91 and i kind of got screwed cause of it

Since the longblock came from a junkyard and I wasn't there when they pulled it from the car I can't be sure if it is a 90. Does anybody know if there is a way to know what year the engine was manufactured (not just the car but the actual engine)?

I know what your talking about, there were two diff size spouts on the cranks for the timing gear. The only problem is, I think the gears have different amounts of teeth. That could give you some serious problems. I'd look into that before just slapping one on there and cranking it over.

Yes, on the cylinder head, it has a stamp on it that tells you what year the motor/head was made it looks like 9/0 if it is a 1990 motor/head.

What i was thinking is that the internals are all the same, so if i slap the other gear on it shouldnt make a difference even though it has different amount of teeth on it, that is prolly just cause it is a smaller gear. So shouldnt it work. or i was thinking I may have to change the Cam gear to, instead of just the gear and pully.

All input is appreciated

So does anyone know where I can order this gear and pully from.

the different number of teeth will make a difference even if the internals are the same. the different number of teeth means that the gear is a different size, and so the cam gear to crank gear ratio would be different. So, if you get a different size crank gear, then you'll need to get the matching cam gear. If you don't then u'll eventually smack all your valves w/ your pistons. I'm in the middle of building a A6/Y8 motor, and finding problem after problem. Anybody have a good Y7 bottom end they wanna get rid of?
