Build date question

[b5cuda]

Hello gang, I'm trying to narrow down the month my car was built.  Came without fender tag or door tag, just vin (BH23G3B146463).  I'd like to get a replacement door tag but don't know which month.  Can we make an educated guess based on the build number?

When you contact ECS for a new tag, they may be able to help you with the date based on their data base...

Thanks Alan, I'll give that a shot

That was the ticket!  Already got a reply from ECS - the build month is 9-72.

They have a great group of guys running the show over there
