Scott, as much as you've helped me over the years I made sure I snapped a pic of the block pad...I have'nt taken the paint off the pad and it's tough to get a good pic... As far as I can see the pad reads...Top row: 426 T PHC Bottom row is tough looks like : - 1- Depending how far we're going into this freshen-up I may try and talk the owner into stripping the pad for a better view...
