Might have screwed up--------
Thanks guys! I think 26" will be about the max for the rear but i will check further. I saw the thread to change to an AOD transmission but I am committed to my original 904 with master rebuild and Transgo-2 kit. By researching the forums it looks like I will need a 37-38 tooth transmission speedometer drive gear for 26-27" tires. Still checking things out-------:burnout:
