How many teeth on my flywheel??

I have a 65 coupe that I will be swapping a 93 LX 5.0 T5 into. I have the complete donor car. I want to order a 28oz flywheel for the T5, but don't know how many teeth the 93's FW has. 164 (most likely) or 157. I can't pull the tranny to count the teeth this week but wanted to order the FW to have by the weekend. Is there any way to figure out how many teeth are on the FW without actually counting?

Thanks for any help!
