Looking to learn a bit about Mopar transfercases used on big block trucks in the 70s.
I believe they went from the divorced tcase to the married tcase in the early 70s. Anyone know what year it changed?

Was the married Tcase the NP203 and was it 2WD/4WD/N/4WDLO and was that used behind all of the big blocks, manual and auto?

Was the NP435 the 4spd transmission used behind the big blocks and did that stay the same through 78?

Any info is appreciated - Z

 

i'm not supposed to give out names of other sites according to this forums rules. but i think it would all right to say that allpar.com might have the info you need

 

Thanks. I've been on there a few times but I'll check it again.
