any of ou guy's running the mile marker part time kit in your 203's?? i have a 203 in my 77 powerwagon an was thinkin of swapping in a np241 i have but hve heard the input shaft is to short?? the truck is goin to me my daily driver/mud toy, i would like to have part time 4wd back lol.. i will also be swapping to d60's... is the 203 a stroner case??

If you really want part time, get a 205..

i got 1 but needs a center bearing. dont want to fork out the cash now to rebuild it at the moment.. the 203 seems to be workin but am just wondering about the part time kits

They will work but junk in my opinion, I would use the np241.

I had one in my 78.It was in another Ram that I bought for parts.I plowed and put at least 40K on the setup.Only problem I had was I snapped some bolts in the frt hub once.I plowed and drove it every day fro at least 5 years.Rocky

If you're strapped for cash, put the part time kit in the 203 and don't look back. Eventually it'll have trouble staying in 4wd and will pop out when you least want it to but it'll work well for awhile provided the t-case is in decent shape to begin with.

The 203 has a different mounting bolt pattern than the 241 (or the 208 and 205's) so you would need to either swap transmissions or at least the tail-shaft with a newer model trans that has the correct bolt pattern.

No they don't. They bolt to any dodge 4wd trans. Pulled a 70s 4wd 727 That bolts to a 203 off of a 241. Bolts rite up

Yes, they do

The 203's use an unique trans adapter, the 241 will require an adapter from a 205, 208, or 241 equipped auto Dodge.

The 727 output for the 203 will be too short for the 241, you'll have to get the right trans output for a 208 or 241 and install it in the 727.

About 1/2 down in this post you can see the difference in the 203 and 208/241/205 bolt pattern and shaft length difference:

Here is an image to show the difference 203 on the left 205 on the right:

If that's the case how is hp383 running the Stock 93 T-case with a 440/727.

Simple - tailshaft w/tail housing swap

is that a dodge 205 or chebby 205?

Dodge 23-spline

Nope. Stock 70s bigblock 4wd trans and Stock 93 Transfercase. Read slowly.
They are BOLTED to EACH other.

Fastback66's garage. And his own garage. Im in thwarting process if swapping in a 518 for him. there's half inch to an inch diff in output shaft length. Otherwise it bolts up.
