I have this question .I have a np205 w/4speed that came out of my 71 k5 which I never drove and just got a 69 short bed w/ a 3speed and a np203 I think. Its all orignal and Iwant that 3 speed out but dont know which t-case is best to use. dont know the diffrencs of the two thanks

Use the 4speed/np205 set.The np205 is the most sought after t-case.They are almost bullet prof.You already have the set up so just use what you have.

The `69 prolly has a Rockewell t-case.It wouldn`t be a NP203.They never came out until later and I`d steer clear of those anyway.I have a`71 3spd K/10 and it has a NP205.I believe`69 was the last year for the Rockwells.Blazers came with Dana30 t-cases behind the 3spd.But,trucks I`ve seen had the bigger t-cases.Is the`69 t-case real teeny?

69 Blazer three speed manual trans would have been backed by a Dana 20 transfer case not a Dana 30.

Thanks for clearing that up.I always forget what they are called.Never gave them much attention other than yanking them out.Dana 30 is a Jeep axle,right?

Dana 30 is a sewing machine axle.

I agree.A Husquvarna sewing machine,right?The Jeep is the most capable offroad vehicle made,once you toss the motor/trans/t-case/d-shafts/axles and stuff Chevy stuff back in and under them.
