More progress on the 68. Motor and trans are in the frame. Fuel line is hooked to the pump. Trans cross member bolted down and hooked to the 700R4. 1 piece drive shaft is marked for cutting.
Now the fun begin's. Getting the cab ready to set but first I have to load it onto the ramp truck for our local club picnic this weekend!

Do you know how to measure for a drive shaft? I was taught how today. It was a simple thing after looking and see a pro do it.

Stick the old drive shaft into the transmission all the way then pull it back about a inch. Then measure from the cups most forward spot on the yoke to the most rearward spot of the pinion cup. Mine will be 55.5" long. It will have 1" of travel this is with the tires on the ground.

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
