lowering blocks on belvedere?

Hi i want to get a set of lowering blocks for my 66 belvedere sedan, 2 or 3" i think, does anyone run them on the rear?? I also plan to lower the fronts couple inches in the front by adjusting the torsion. it's a four door sedan and i'd love to have a nice lower stance and wanted to ask some reference and tips to getting the right one.

thank you!

I've never used them, but you may encounter some clearance problems with a 3" drop, especially with the pinion snubber to floor and bump stop to rear end housing. It might be a good idea to crawl under the car supported by the rear axle on jackstands and measure the distance from the snubber and bump stops to the contact points.

Mine 67 lowered itself about 3 inches when I took it off the trailer on Monday, and the torsion bar ripped through the K member. That REALLy sucked.
