Big block rebuild - where do you buy your parts?

Just to get an idea use the end of the calipers, the little part sticking out the bottom, have that on the piston top and the edge of the caliper on the deck..

AND before anyone bitches... it won't be 100% accurate but should get you within a few thou so at least you know what you are looking at :)
