I just bought a great running '66 C-60 and have a few questions since everything is way bigger than I am normally used to (Suzukis).

1. The first question is about the two speed rearend. What is Hi and Lo, out or in (they aren't labled)? I drive big rigs around the work yard, so I understand how 2-speeds work, just I'm afraid to "experiment" for fear of breaking something. And is there a specific way to shift (it's a 4-speed)? The instruction sticker says somthing like switch to Lo and THEN shift transmission, or shift transmission then switch to HI (or visa versa) which has me a little confused.

2. It has the L6 - 292ci and I was wondering if anyone has put long tube headers from LMC on theirs? Do they clear the mounting brackets? From the pictures in their catalog it looks like they would, but I don't know if the motor mounts are different than a normal C-10 or 20.

3. I am considering replacing the motor with a 6.2L diesel.
A. If it is possible to mount the diesel to the current 4-speed tranny, how do you think the different RPMs would affect the driving.
B. If I replaced the motor AND tranny with an automatic, would that combination work with the 2-speed rearend?

It currently has a long flatbed on it, but I am hoping to mount a sleeper cab and shorten the flatbed so it's just long enough to haul fourwheelers, snowmachines, etc... Not quite a daily driver, but will still be driven a lot so any issues that you may have come up against that I should consider would be great. Any suggestions, thoughts, or comments would be appreciated. Thanks.

ALSO: Does anyone know if they originally had sleeper cabs as an option? If so do you know where any pictures of some are?
