19Fordy,
Thanks. I used the twist bar/long pointer for the torque measurements. It seems that as I got near 50 psi, attaining the 50 moved away. I have a modern torque wrench, but it sets at 25 right now and I was too lazy to spend the time to crank it up to 75.

I suffered a little yesterday pulling on the wrench. Thanks for your opinion. I saw a number somewhere that a 7/8th nut design limit is 120 psi.

I just realized that I chose cotter pins new from my general pin jar. The Merc is a national car: I assume the cotter pins are checked for proper size?? If I have to change them, I want to get the torque correct.

The frame has a thick coat of white stuff under the black. Perhaps this is crumbling under the torque load??

Thanks all for your assistance
Clem
