76 4x4 Dodge? Info?

i had a 77 ramcharger. full time 4 wheel drive, automatic trans, no locking hubs. the guy i had gotten it from had taken the the front driveshaft off because of transfer case problems causing the engine to overheat...or so he said. we never did get it working right. make sure to use the same size tires all the way around all the time.
