Sorry for the rookie question, fellas. I have searched and found lots of people who have done this but I haven't seen a part number/description or anything. I'm looking for a definite answer before I lay down money for the wrong part. I'm using '36 radius rods in the rear of my Model A with a '37-'41 front spring. I am wondering what year(s) shackles i can use that will fit both parts correctly. I would prefer to use original Ford shackles or a high quality new part, possibly, if it's made in the USA. Any advice is appreciated. Thank you.
Use 35-40 front shackle set, you'll have to shorten the 36 radius rod bores to the width of the front spring. The shackle bores are the same front and rear spring eyes and brackets.
