1937 Terraplane spring shackle sizes

barrysweet52

I would appreciate confirmation of the correct shackle sizes for the two front spring shackles, and also the rear shackle on the rear spring. I have found some for sale at a good price and want to make sure I get the correct ones. One never knows if a previous owner has changed the sizes. I understand that you measure the shackle center line distance. My shackle measurements starting from near the front bumper are 2 & 1/4", 3" and 4" near the rear bumper. Dodge cars use some of the same shackles, but dont seem to worry about LH threads at certain locations like Hudson did. Thanks for sharing, regards, Barry
