66 c10 rat

I know what you mean about not seeing to many 60-66 trucks in Ohio. These trucks for the most part have rusted into their surroundings! When I moved from Ohio to Colorado a few years back the amount of old trucks available really opened my eyes.

I wanted to mention that from a safety perspective 1-1/2" rear lowering blocks are the most you can go with if your are running 15" wheels, due to scrub line issues. Otherwise if you get a flat rear tire the trucks lower shock bracket will be diggin into the pavement..... not a good thing.

If you want to go more than 1-1/2" then you need to increase wheel diameter.

So if you have 18" dia. wheels you could use 3" blocks, as follows:

18" dia. - 15" dia. = 3" diameter difference,
3" dia. / 2 = 1-1/2" radius difference,
1-1/2" increase in wheel radius + 1-1/2" blocks = 3" blocks

Post up some photos of your truck....
