What thread are the three screws that mount the OTA to the rear cell - I
have just had a company make me three cups to reinfoce the damaged
mounting point* and the screws are just a bit short - unfortunately the
engineering company only has UK and metric threaded bolts and not US
threads - also tried a few local hardware stores without much success -
phoned Meade and very unhelpful -
all I got was, "...sorry, but Meade no longer support the ETX105".
Thank you and regards,
Mike here: Perhaps Dr. Clay Sherrod knows the size. Over to you, Dr. Clay.

The tiny hex cap head screws are 6-32 x 3/8".
