Hi Mike,
Thanks for the info, but I think your reply should be directed to David
I would like a copy of the article you published on the C8AX please.
I changed my diff ratio in one of the trucks and fitted higher ratio diff heads from a gun tractor, increased the road speed by approx 10 mph.
Don't ever loose a front wheel cylinder (I misplaced one about 20 years ago

) and I'm still looking for it

: They are peculiar to this model only. Hey they do good 180 degree brake test with only one front brake connected
I will see if there are any spare wheels next time I visit the trucks, but I don't think I have many 16inch rims either.
What are the chassis numbers and dod on your trucks guys?
Mine is......
CHASSIS MODEL C 15441
CHASSIS SERIAL XH 8448-322
ENGINE SERIAL FR 3863983
DOD 5-4-43
Cheers,
Brent D.
