My '26 Master's tires are shot and I'm also planning to drop the oil pan, so I brought my jack stands out of storage because I thought they'd eventually come in handy. They're Harbor Freight Orange 6 ton rated probably circa 1982.
Looking at the new Harbor Feight jack stands I notice they now have a triangular shape insert that holds the column in place in addition to the pawl.
A little searching on the web and I found out why---it was found to be hit or miss how much the pawl surface will engage the ratchets on the column, so it could fail, and tragically has failed on some of these jack stands, hence the design change.
Not wanting to end up a pancake----this is supposed to be fun, right?---- I figure a set of new jack stands is in order so my question is, should I get 3 ton rated jack stands or 6 ton rated jack stands for my 26' Buick? It's a big heavy vehicle but does it require 6 ton jack stands?
Which size jack stands do you use on your pre-warBuick?
