Ed they're .75" pitch yes all pins and bushings just like a real 1 . In the1st & last pics , you see (barely) .375" bushing pressed into the rails on 1 end . the 2nd pic you see a .25" pin pressed into the master link half . I still have 2 setups to do on the pads yet then a little forming for the curl under pat of them in front of the grouser bar . The pads scale to just under 2.25" wide so I just used 2.25
. the links are going to take me a week to get completely done . Then to press all of it together
