1997 dodge ram 1500 sport 4x4 transfer case issues.

I need a transfer case for my 97 dodge ram pick up sport. I have replaced this before but the housing doesnt quite match up ad is throwing bearings out and destroying the guts of my t-case. 231d 272 gear ratio 5.9l 360cid.

Quite a few listed here.
