I was very glad to see your above post, particularly after reading the negative issues the moderator raised in the previous one. I intend to use L&P couplers exclusively.
Can you tell me how far apart the blocks were usually located? At or near the corners of the car, ala buffers, or near to the pocket?

Do you use this on your cars? Any pictures?
I do not use dead blocks on my cars, but only because I do not have any cars yet.

I'm sorry that I cannot find any good photos of dead blocks. I just spent about 30 minutes searching the web, but the best I could find was a very grainy photo of a drawing that may or may not show anything useful. So short of photographing and posting copyrighted material, I can';t come up with pictures.
They're super simple to describe, however. Basically, they were two blocke, either of wood or cast iron, mounted to the end sill of a car on either side of the coupler. I think, but I'm not 100% sure, that they would line up with the center sills of the car, to transmit buff forces in a direct line. Since they're mounted to the end beam, they're usually above the coupler, but relatively close to the center of the car. They were long enough that when the draft springs compressed, the dead blocks would touch.
Of course, not all cars had dead blocks. One thing to remember about L&P couplers, though, is that they worked differently thana lot of us think. First off, they didn't swivel - they were mounted to a shaft that (usually) was able to slide in and out, but not side to side. Second, the links were short enough to allow the coupler pockets to touch. Thus, when shoving a train, the coupler faces would be transmitting the force, not the links.
