There's under 1/8 inch play when I used used a 24 inch screwdriver to pry. But my guess is that it's not in great shape.
Since O'Reillys & AutoZone (Anchor #8095) is $33 + 10% tax (and special order), I see where I can get the exact same part at RockAuto for $11.31 + 8.50 shipping or $16 shipped (Ebay retailer). Then I'd just install it next time I get the truck on jack stands when the weather gets a little better.
Looks like very straightforward R&R, could use my electric impact wrench on the four rear crossmember bolts.
