Ordered a couple new trunnions on sale from TRF and glad I did. Pulled and
cleaned up the original Stanpart stamped trunnions and the new bolt from the
suspension kit has a lot more slop in the old one than the new. Will keep
original in my museum originality shelf. It will sit right next to the old
western Thomson English thermostat that I pulled out. The previous owner who
had the car for 45 years said he never had to change the thermostat.
Next step, reinstall front suspension components.
Cheers and thanks,
Jim Henningsen
