In bought new correct to year shackles for my 1912 touring. One set has T246 on one side and T229 on the other. The other set has T91 on one side and T91 1/2 on the other side.
Which set goes on the front and which one goes the back?
Thank you in advance for your help.
Rear springs are wider so the set that is longer should go on the back. Shorties on the front. Not sure about the numbers.
They're different numbers because one of each pair should be drilled for an oiler.
Ditto on longer in rear.
