So, my jbeam skills (as many of you in my PMs can attest) are rather shitty and I need some help figuring this out. I'm working on a small project that may or may not end up getting released -- it's an early 1960's truck with a two-speed rear-end and five speed manual transmission, I suppose it'd be much easier to just make it a ten-speed with two reverse gears, but I'd like to stay faithful to the real truck and actually make a working two-speed rear-end. I'm still in the modeling phase and haven't started jbeaming anything yet, but any advice or ideas are very welcome.
I am no expert but the easiest approach to this would probably be a HI/LO transfer case similar to what is found in the offroad trucks. I've never done it myself but I'm sure the ratios can be adjusted to your liking.
