Ulf,
Your 6500 is actually a 2 ton truck (2-1/2 ton trucks are Series 7-8-9-10).
Here is what I found in my Parts Book...
Tie Rod Ends 55-59 Series 5-6 (exc. HD)
left (1-16 LH thd) (5 OL)...p/n 609747
right (1-16 RH thd) (5 OL)...p/n 609748
Inner Wheel Bearings Assembly
55-59 Series 5-6 (shaft dia. 1-3/4") (Hy C125298WA)...p/n 7450335
Outer Wheel Bearings Assembly
55-59 Series 5-6 (shaft dia. 1-1/32") (Hy A131224Z)...p/n 7450336
The parts from Classic Perform are for the small trucks...
I don't think the ID is right on the NAPA Bearings.
Can you read the numbers off of your bearings?
Hope this helps,
Mike B
