I will be installing a new 13. 25 Con-O Southbend clutch in my 99' 5 speed very soon because it slips when towing. My question is... IF the 5 speed were to belly-up AND I decided to swap to a late model 6 speed at that time, would I only need to change the disk to get the clutch to fit? I only want to make this major clutch change once, but I am just looking ahead...
