That would be correct for the 89 and up trucks but the 3.54 wasn't available in the 1 tons until 89. Or until the cummins came out.


OK, I stand corrected. My 84 crew cab dually has 4.10's, but I am sure they were changed at some point. wave


The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
