Windscreen corner brackets

[bbh]

On the Healey 3000 on each corner of the windscreen frame the top and bottom frame rail is attached to the side rail by a small corner bracket and 4 small countersunk screws.  These pull the frame together and (hopefully) give a tight mitre joint at each corner.

Does any-one know what size these small countersunk screws are?

I have the original brackets in OK condition which I would like to re-use, but not all of the original screws!

Don't know the size, but ahead4 Healey claim to have them - at 20p each !

 I need to phone them, but I suspect that they maybe metric and sized for the new repro brackets, but I could be doing them a disservice, hence the call.  

 I believe that the screws are 4BA and my originals are sized between 4.95mm and 5.35mm long (clearly tight manufacturing tolerances there!)
