[quote=Greg Brown]If you go back up to the 3rd post, you'll see that I attached pictures of the rear mount in my '49 3100 w/ SM420 and TT. I'm pretty sure this is all 100% original, though I've learned you can never be sure after 70 years.[/quote] Thanks Greg for your post, mine is setup the same way as yours. Keep in mind that 1/2 ton trucks with sm420 are not depicted in the assembly manual.
