7 1/4 to 8 3/4 swap question

The shock plates are different between the 7 1/4 and the 8 3/4 due to the larger tube size of the 8 3/4. The holes for the u-bolts on the 7 1/4 shockplates will be closer together than the 8 3/4. There are 2 options, either find a set of shockplates from an 8 3/4 or hog out the boltholes on the 7 1/4 shockplates you have to accept the larger u-bolts. I personally would get the right shockplates, but either would work. Good luck on your project, Geof
