18s40385 this # should be the same as Vin#
3925660 this is the casting # of the transmission
Should be therd # of the date look like P8P??
P= Muncie
8= 1968
P= September
??= day
only in 1968 You can't know if it's M20 or M21 Or M22 wide ratio or close ratio you need to open the gear box.

Thanks for the fast reply and yes i did not give the third set of numbers and it is
P8R and i am summing that P=muncie// 8=1968 and R=????. All in all its a 68 vintage
transmission. If you could define the "R" for me i would appreciate it.

thanks again for all the info and help
