The grey portion's length is 9/16th inch, diameter is 3/8th inch.
Metal portion's length is 1/4 inch, diameter is 5/16th inch.
Diameter of the 2 locking ears is 13/32th.
Is there a spring that the fuse contacts, on the end that the fuse holder is not connected to, or anything else inside the fuse port hole?
Thanks again for your help,
Dennis
