I ship a lot of parts with out issue. Package it well, put in the actual weight and measure accurately. If it’s 11 1/4 inches it goes to 12 it’s always rounded to the next inch. If it’s over it’s OVER. No problems. If the shipper tries to cheat a little on weight or size it’s no one’s fault but their own…Maybe a couple of the big sellers on here will comment on the shipping costs and what if any additional charges the are getting dinged with.
