Lubes and Capacities

[joe dirt]

I've searched, but can't seem to find definitive answers. I have a 1985 K20 Scottsdale with a SM465 tranny, NP205 T-Case (swapped in by previous owner) and 9.5 SF 14bolt rear, 10bolt front.

I want to service the drivetrain and plan on using non-synthetics. What type (weight) of lubes should I use in each and what are the capacities?

Thanks,

OK, it appears that 80W90 will be fine for the entire drivetrain. What about the capacities in quarts?
