I think the cold is done, mid 50's in the morning when we tee'd off at 7.
I wore my loud Caddy Shack long pants (always good for a laugh) and was wishing I was in shorts by 9.
But the old car ran great, highlight of the day.
Never seen that metal ring, wonder if it's a 70 only thing.
I seem to remember the repo I put in had molded in metal base.
Check DMT description, I trust him
