Stop in for a cup of coffee

Took the Ford pickup that's close to 300k on it. All it needed for safety inspection was front pads.
Failed emissions. Code reads converter or selinoid. Off to the trans man tomorrow.
Meanwhile I picked up the 07 Blazer, sometimes wife's shopping vehicle 132 k.
$1095.00 front pads, left wheel hub. Lower ball joints both sides.. oil change, eninge flush and refill. New Battery. Existing one was 9 years old.
