I killed my 203 this past weekend :banghead: ..so-
I have an 84 K5 blazer for parts so did the 83-87 blazers come with the 207C or the 208?
The 207C's were 27 spline right? What about the 208's? Were they 27 or 32?

I have a T350 and it has a 27 spline shaft right? so this swap should work right?

Any help will be MUCH appreciated!

The blazers should have a 208 in them. All vehicles with a T350 or later the 4l60e have the 27 spline shaft. The T400 and 4l80e have the heavier duty 32 spline shaft. Your 203 now is a full time case so you are swapping in a part time which in most peoples opinion is a good thing. im not 100% sure if the bolt patterns and all match right up but I think they do.

what doesnt make sence on it? Please let me know so I can fix it, maybe my brain just works in a weird way and other people dont get it :crazy:

i didnt understand the coloring part of it..... it needs a key that says what the colors mean.

 

[Dark Eternal]

it does, at the bottom of each case it lists what vehicle it was in, and colors corespond.
