Anyone out there know what size and pitch the three screws are to attach the two halves of the control head together on a 59 TR3A?
Nothing in my assortment seems to fit and I do NOT want to strip the brass inserts.

More then likely, they are British Association (BA) threads (https://www.britishfasteners.com/threads/) if they are smaller then 1/4". A lot of the screws smaller then 1/4" on the TR3 are BA threads. See the chart I linked to. The only sizes that I've run across so far are 2BA and 4BA. If the screw measures about 0.142" it's a 4BA, 0.185" = 2BA.

I had one measured at fastenal a couple of years ago and they gave me these numbers: M 2.5 x 60 x 6 Unfortunately, they only sold them in 100's. I made do with the old ones.

Those are the grub screws holding the control head in the steering column...I get the feeling that Gordon is looking for some other screws...or am I totally off-base??? :confuse:
