i just picked up a 1970 shortbed pickup, manuel tranny, not sure ont he transfer case. its got a driveshaft going out of the transfercase, and to a bracket, with another driveshaft coming out of that. whats the deal? can i take that braket off and just run a longer driveshaft for a better angle? and also, its got 56 inch springs int he back, is that normal for a 1/2 ton shortbed? the front rear spring mounts are some custopme made jobs that i am gunna take off, and i have a rear lift springs from a blazer, so i will probally just move them back. thanks.
