G'day

Could someone tell me what the thread size is for the action screws on Stevens 200 actions???
I have a .223 and have just ordered a Boyds stock for it.It says on their Web site that the action screws from the old plastic stock will not fit and I will need to order some from Savage that are designed for their wooden stocks.
I live in Australia and ordering anything from overseas is a pain in the you know what.
I'm sure I must be able to track down some screws here but I need to know what size to look for , both lenght and thread size.

Thankyou for your time.
