I say don't bother with the JB Weld. Get a tube of GOOP, automotive or
plumber type. Put the speedo in place in the IC housing. Use the GOOP
liberally to cover the corners of the speedo case, overlapping the  IC
housing. The GOOP will hold it together forever but you can peel the
GOOP off in the future if you need to open it up. I have used it on many
vanagon speedo and tach mounts with broken out screw holes. No screws
are needed when the the GOOP is used but if any of the corners are still
good, use those screws and leave the goop off those corners.
