Just finished doing chevy/rufs and hi steer on my 85 4runner project and before I get a longer drive shaft made, I was thinking about doing a dual t case so I don't have to change my driveshaft's later on. My question is what will I need other than the driveshaft adapter from advance adapters, to run a dana 300 behind a toy case. How hard is this set up to run? What kind of crossmember options do I have? Is it hard to make a custom crossmember? Thanks in advance
