| I think they had 34” tires. Maybe could’ve been ordered with 38s. You can use a step up rim to put 38s on the 34wheel.
Would be better hydraulics than the late 60s ones. Not that they were much different but I have a 69 and an 8 and the 69 is a side console. Seems to have more flow. Runs things with hydraulic motors a little better.
The 71 and 72 would’ve had a better injection pump. They moved away from the cb pump.
Other than that not much difference I don’t think.
What do I know though. I wasn’t even alive when they were built! I’m an 83 model. | |
