You will want to try to double check these measurements since they came from a rod that was broken that I repaired. So they may be a little off. Spring bobber is 2.875” out from the first guide on the blank. First guide from the tip of the spring bobber is 2.875” (calling this the second guide), 3rd 5.125, 4th 8”, 5th 11”, 6th 14.5”, and 7th is 18.5”.
Make sure to find the spline and I would do a static test before securing down the guides.
