Man,they were stumped.This was in`77 before anyone around my area had tires that big.  |
haha great story.. i might have to use that one someday and do the same you did
i have 35 inch tires, 700r4 tranny, 205 transfer case, 4.56 gears. one thing i also have a problem with is the length of my speedo cable. the 700r4 is 2 1/2 inchs longer then the 350 that was in there. there was a shop here in town that made cables, hade a dyno in there shop for setup after big tires and gears or whatever. they closed and i cant find anyone that knows about it.
